CC3551E: FW Cash during Iperf test

zhong wei — Mon, 19 Oct 2026 07:22:02 GMT

Part Number: CC3551E

Hi Team:

When using the latest SDK version for iperf testing, we still encounter the FW-CRASH issue. Below is the relevant test information:

1.The SDK version used for testing is simplelink_wifi_sdk_10_20_00_39.

2. The CC3551E roaming test uses the LP-EM-CC35X1 Rev A development board, running the network_terminal example.

3. TCP iperf testing is performed with the following configuration:

CC3551E iperf -s -i 1

PC iperf -c 192.168.10.49 -i 1 -t 6000

After some period of time, an FW-CRASH occurs and Wi-Fi becomes abnormal. Based on current testing, the issue can be stably reproduced on a TP-Link router. The following files were captured while reproducing the issue with this router:

- Logger outputs: 2026_09_09_105835_stream.csv and stream.csv. The abnormal log is in stream.csv.

- debug.log is the console UART output.

- wifi_capture_20260908_225356-Decrypted.pkt is the over-the-air wireless capture covering the entire process from the start of iperf until the CRASH occurred.

We previously submitted a report regarding this issue, but unfortunately, it remains unresolved. As our product is about to be launched to the market, time is of the essence. We kindly request your team's priority support in investigating this matter. Please let us know if you need any additional test logs or environment details to help with the debugging; we are fully committed to cooperating with you.

Jerry Kuo — Mon, 19 Oct 2026 06:29:21 GMT

Hi team,

Thanks for your comment. Could you also provide instructions for CC3301 as AP mode ? If CC3301 act as AP role, how to change WiFi channel ?

CC3230SF: equivalent MCU that supports BLE as well

pragash sangaran78 — Sun, 18 Oct 2026 10:41:56 GMT

Part Number: CC3230SF

Hi TI team,

We currently have a product in production that uses the CC3230SF12RGKR (SimpleLink Wi-Fi MCU).

We are looking for a low-power alternative that supports both Wi-Fi and BLE. Ideally, we would prefer a part that is:

Pin-to-pin compatible (drop-in replacement) with the CC3230SF12RGKR
Software-compatible, so existing code can be reused with only minimal changes

Is there any recommended MCU from TI that meets these requirements?

Thank you in advance for your guidance

CC3351MOD: M2-CC3351: Streaming video crashes cc3351 driver part 2

David Soberanis — Thu, 16 Jul 2026 22:09:23 GMT

Part Number: CC3351MOD

Hello all.

Last year, I made a post regarding CC3351 WiFi module that would crash during video streaming.

Post: https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1510211/m2-cc3351-streaming-video-crashes-cc3351-driver

Here is another post that has the same issue: https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1508195/cc3351-wi-fi-locking-up-while-downloading-atmds62levm-m2-cc3351-linux-ti-staging-6-12

The advice given was a workaround that changed using out of band IRQ to in-band IRQ in the wifi module's device tree.

This workaround (although very helpful) does not fix the issue completely. We still get occasional full disconnects when streaming video or applying an update over the air to our product.

Here are the new error logs we see in userspace

cc33xx: WARNING Unable to flush all TX buffers, [10667.746314] wlan0: Connection to AP f8:fb:90:12:11:06 lost
[10668.273071] cc33xx: WARNING Unable to flush all TX buffers, timed out (timeout 500 ms
[10668.785061] cc33xx: WARNING Unable to flush all TX buffers, timed out (timeout 500 ms
[10669.297040] cc33xx: WARNING Unable to flush all TX buffers, timed out (timeout 500 ms

Here is a recap of the issue that was confirmed to be accurate by TI's WiFi firmware staff ( Sabeeh Khan1 )

=====================================================

CC3351 fw tries to stay in power mode LPDS whenever possible to lower power consumption
- transitionStart PWRMGT_POWER_MODE_IDLE1 ==> PWRMGT_POWER_MODE_LPDS. need2Wakeup = 1
During video streaming power mode changes to idle to send a frame then returns to LPDS between frames
Out of band GPIO pin receives an IRQ whenever power mode changes
Thus power mode switches repeatedly between LPDS and IDLE
Some unknown source causes the change from LPDS to IDLE to fail
- Transition to sleep/lpds not allowed. already in PWRMGT_POWER_MODE_IDLE1
FW keeps trying to change from LPDS to IDLE at very high frequency
Out of band GPIO cannot keep up with the rapid IRQs being sent
This causes a desync between the CC3351 FW and Linux Driver
CC3351 FW notices the desync and resets itself
- --- HandleResetCause ---
- Reset cause value: 0x3
Linux Driver notices CC3351 FW is not responsive
Linux Driver then issues “cc33xx: ERROR INTERROGATE command failed”

=====================================================

To consolidate everything, here are the logs from last year as well:

Here are the parsed logs from last year as well: https://drive.google.com/drive/u/0/folders/1irMfbw7kr3gWQuiARuL3DWkaQhM2LmkS

=====================================================

I believe there are two ways to approach this
1. A better workaround

Since the issue stems from "During video streaming power mode changes to idle to send a frame then returns to LPDS between frames." We can avoid this if we can toggle CC3351 firmware to remain at IDLE power permanently. If this is possible the firmware will have a low chance of failing to swtich between power modes since it will remain on steady IDLE power all the time.

2. Fundamental fix
If the firmware can be updated to prevent this bug "

Some unknown source causes the change from LPDS to IDLE to fail
- Transition to sleep/lpds not allowed. already in PWRMGT_POWER_MODE_IDLE1"

Then the issue would be resolved as well.

Resolving this video streaming issue is critical to our success. We are going to launch thousands of products this year that rely on CC3351MOD to reliably stream video. We would greatly appreciate your support in addressing it.

RE: CC3301: How to fix WiFi channel

Josh Smith — Fri, 16 Oct 2026 16:29:51 GMT

Hello Jerry,

The CC3301 device associates on whatever channel the AP broadcasts. If you would like to fix the CC3301 to a specific channel, this would need to be done on the AP side. Most likely you will need to disable auto-channel selection and force your AP to broadcast on whatever channel the customer desires. After connecting to the AP you can check the channel it is associated to using "iw wlan0 link" assuming this is a Linux OS.

Best,

Josh

CC3551E: Per-channel survey scan and passive-only survey scan

Jordan Malenko — Fri, 09 Oct 2026 11:38:27 GMT

Part Number: CC3551E

Hello,

We use CC3551E with SimpleLink Wi-Fi SDK and Toolbox 10.20.00.39.
We use Wlan_Scan() for site survey scans, and are curious whether the following two features are already available in the SDK, or would need to be added:

Survey scan on selected channel or channel list
By default, a single survey scan returns at most 18 results (CME_SCAN_MAX_DIGEST_RESULTS). We want to be able to scan one channel at a time and merge the results in order to reduce result truncation in dense WiFi environments.
There is a WLAN_SET_LISTED_CHANNELS_FOR_SCAN definition in wlan_if.h, but it is not used in wlan_if.c.
Is this WLAN_SET_LIST_CHANNELS_FOR_SCAN planned or available in a newer SDK release?
Is there a different way to restrict one-shot survey scan to specific channels?
Passive-only survey scan
We need a scan that sends no probe requests on any channel. Is there a supported way to force a survey scan to be passive on all channels?

For now, we have patched the host stack locally.
We added a one-shot selected-channel list that Wlan_Scan() uses for the first feature.
We added a forcePassive flag inside scanCommon_t that puts all channels in the passive list for the second feature.

However, we would prefer an official solution so we can drop our local patches.
If necessary, we can provide our patch files.

Thank you and best regards,
Jordan

RE: CC3551E: Per-channel survey scan and passive-only survey scan

Jordan Malenko — Fri, 16 Oct 2026 14:23:52 GMT

Hi Sabeeh,

For 802.11d we might be able to work around not being able to do passive scans.

However, the fact remains that we still support passive scanning in our solution. Also, all previous SDKs we've worked with have provided both active and passive scanning, so we would appreciate it if it was supported in the CC3551E SDK as well.

Best regards,
Jordan

CC3501E: SDK Migration: Docs says "need Factory Programming" - why/when/how?

Martin Egholm — Fri, 16 Oct 2026 08:08:42 GMT

Part Number: CC3501E

Hi there,

I've begun migration to the most recent SDK, 10.20. In the docs one can find the "Attention"-box:

"If you have an already activated device, you will need to perform “Factory Programming” with the toolbox provided in the sdk before being flashing via CCS."

[https://software-dl.ti.com/simplelink/esd/simplelink_wifi_sdk/10.20.00.39/exports/docs/wifi_ble_uppermac/html/migration/cc35xx-sdk-migration.html]

Why is this necessary? (maybe that is not stricly necessary to answer, depending on the answers to the following questions...)

But then, how is it done?

If I run the Toolbox UI, is this "Factory Programming" related to the "Load Default Images" step after selecting "Programmer":

...or is it related to the "Flash Factory Reset" checkbutton in CCS -> SysCfg -> Vendor Utils -> Programming:

...or is the only way to launch the programmer from CLI with the parameter "factory_programming":

.\simplelink-wifi-toolbox.exe programmer factory_programming --activation_type sdk_example_key --flash_type IS25WJ064F

And what if the product is with a customer and we only support OTA - is it at all possible then?

What are the risks from omitting?

I hope you can shed some light on this. Thanks.

Martin

CC3351: CC3351: Internal SRAM / RAM size clarification for CC3351

Chang Dylan — Fri, 16 Oct 2026 06:25:40 GMT

Part Number: CC3351

Hi TI Team,

I am looking into the CC3351 for our upcoming Wi-Fi 6 + BLE 5.4 design.

I searched through the CC3351 datasheet and product page on TI.com, but couldn't find the specific hardware memory details regarding the internal SRAM/RAM size of the CC3351 core.

Could you please clarify:

What is the total size of the internal RAM/SRAM on the CC3351?
How much memory overhead is required on the host processor side (Linux/MCU) for the Wi-Fi/BLE driver and stack?

Thanks and best regards!

Dylan

CC3351: Does CC3351 support MQTT keep alive mechanism?

Jesse Wang — Fri, 16 Oct 2026 05:31:58 GMT

Part Number: CC3351

Hi TI expert,

My customer is using CC3351 and please help confirm the following questions about implementing MQTT:

Can the CC3351 maintain the TCP/MQTT connection, including the MQTT Keep Alive mechanism, while the Linux host CPU is suspended and the DDR is in self-refresh mode?
Can the CC3351 detect an incoming MQTT message and trigger a wake-up signal through a GPIO to wake up the host CPU without requiring the host CPU to be running?

We check CC335x datasheet in “CC335x SimpleLink™ 2.4GHz and 5GHz Dual-Band Wi-Fi 6 and Bluetooth® Low Energy Companion IC datasheet (Rev. C)”) that CC3351 supports TWT feature and itself has an HOST_IRQ_WL interrupt GPIO to wake up the host CPU. But are these related to support MQTT keep alive as above questions?

Hi David,

I've reviewed the firmware logs, thanks for sharing those. It seems that the wpa_supplicant is issuing multiple connect commands back-back and consecutively and that is tripping up our device. Ideally, there is protections in our software against this case so I'm sharing a patch for you to test with.

So please do try the attached patch. That being said, I would like to explore why multiple connect commands are being called. Is this something you can investigate on your side? Do you have a wpa_supplicant.conf for review by chance?

CC3551E: Will Ti produce a Module like the CC3235MODSF for the CC3551E ?

gustavo zarba — Thu, 15 Oct 2026 14:45:59 GMT

Part Number: CC3551E

Hi dear people,
Is TI planning to offer a certified module similar to the CC3235MODSF or CC3235MODASF, but based on the newer CC3551E, preferably with an integrated antenna?
I know that some TI partners already offer CC3551E-based modules, but my trust in TI remains unshakable. ;)
Thanks and greetings!
Gustavo

RE: CC3551E: Per-channel survey scan and passive-only survey scan

Hi Jordan,

The simplelink wifi SDK already contains an 802.11D implementation. You can check regulatory_domain.c. When connected to an AP, the cc3551 will extract the maximum power for the connected channel from the beacon frame. It seems you are suggesting that you have your own software implementation of 802.11D, correct?

Let me follow up internally about the scanning per channel.

Hi Luke,

As the report suggests, this product does not support DFS in Master (AP) mode. Only Slave (STA) mode w/o radar detection.

Hi,

Can you share the test report of "EN301893 v2.1.1 (5GHz Wi-Fi)"?

Can you check "EUT Operating Mode : Matser" test was done regarding DFS test?

You can refer this.

Is it works with MCU ?
If yes can we connect with SPI for wifi and Bluetooth through UART
is down my connection are correct.

Hi Sabeeh,

Here is a longer log with the TX buffer error.

https://drive.google.com/drive/folders/1qEpSnBlwJgb0k_UQs-LFAzUPiXlvZYyv?usp=sharing

I included the full dmesg, full journal for this boot, NetworkManager service journal, wpa_supplicant service journal, and kernel logs related to cc3351mod.

[quote userid="313399" url="~/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1665169/cc3351mod-m2-cc3351-streaming-video-crashes-cc3351-driver-part-2/6500588"]Any chance you can give me some steps for me to reproduce this issue? Can you also clarify the setup here both in terms of software and hardware?[/quote]

We are using a custom board for the drone and controller that uses the am62sip and cc3351mod.

The error is hard to reproduce consistently. I have noticed that it will happen randomly even if we are not streaming video. But the time it takes for the TX buffer error to occur seems random, ranging from just after boot to 20 minutes.

If these logs are not enough, we can send two images that configure two am62sips to stream video to each other in an attempt to reproduce the bug.

cc33xx SDK version is 1.0.2.17

am62x Processor SDK version is 11.01.05

Yes, that's right.
