Hi,

I'm using SK-AM62B-P1 boot from SD card and M2-CC3351. I follow the guide but I couldn't connect AP.

Besides, how could I use the BLE of CC3351 to do adversing and scaning device? Thanks.

Hi Jacky,

I've worked on it before, as best of my knowledge try connecting to your smartphone after typing the below command.

udhcpc -i wlan0

before executing sta_start.sh script, check if your wlan0 interface is up by the command ifconfig if not the type the command ifconfig wlan0 up now check if its working or not.

Also make sure your smartphone hotspot settings is the same as your sta_connect configurations. if you given the security WPA-PSK then set your smartphone security to wpa-2.

regards,
Binson

Hi Binson,

It seems that the both wlan0 and wlan01 interface are up. See the attachment .

The images SK-AM62B-P1 used is from here named tisdk-default-image-am62xx-evm.rootfs.wic.xz.

Does the image good for the SK-AM62B-P1 and CC3351?

Hi Jacky,

What you are showing is eth0 and eth1, not wlan0/1. eth0 is ethernet, not wifi.

I believe you are using the wrong image for what you are intending. Can you please use the am62x prebuilt image from this link?

Hi Binson，

It's not the problem with the image.The Processor SDK 10.0 includes support for the M.2-CC33x1 on the SK-AM62B-P1, it must add a 10kOhm resistor in footprint R6 to pull up the WL_IRQ line near the SD card. But the guide doesn't mention it.

Now the WiFi is OK. I know the CC3351 support BLE, so how to use the bluetooth function? Thanks.

Hi Binson，

Now the WiFi sta mode is OK, but I couldn't use the AP mode although I have stopped the wifi station..

Besides, I know the CC3351 support BLE at the same time, so how to use the bluetooth function? Thanks.

Hi Jacky,

For the ap start issue, please comment out 'wep_rekey_period' in hostapd.conf.

To enable BLE, you will need to apply the following patch to your linux kernel: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1413649/am625-cc3301-unable-to-get-hci0-interface/5447126#5447126

Hi Binson，

Thanks for your help. The AP is OK.

I have got the BLE patch from the link you provided before.

I'm new to TI platform. Is there any guide about how to use the BLE patch to make BLE work well? Thanks.

Hi Jacky,

I would recommend you read through the CC33xx Linux SDK. We have much better documentation and support for Processor SDK 9.x instead of 10.x. Have a read through here:
