CC2640R2F: Which RF-PHY settings impact qualification

Kenton McFaul

Part Number: CC2640R2F
Other Parts Discussed in Thread: BLE-STACK, , SYSCONFIG

Good day!

We are developing Bluetooth® firmware based on the simple_peripheral project (using the BLE-Stack library from Simplelink SDK 5.30.00.03 (not the BLE5-Stack)).

SWRA601H (https://www.ti.com/lit/an/swra601h/swra601h.pdf) specifies that the host_test project can be used for SIG and regulatory testing, assuming it utilizes the same "protocol stack and radio configuration" as our custom project.

I noticed there are several PHY-related parameters that can be adjusted (during compile or runtime) to modify particular PHY settings (e.g., transmit power). This leads to two questions:

Which of these features could impact regulatory testing and qualification (i.e., which parameters or settings need to be identical between our project and "host_test")?
Where would I find documentation on how to control these features? (I did find this link https://dev.ti.com/tirex/explore/content/simplelink_cc2640r2_sdk_5_30_00_03/docs/blestack/ble_user_guide/html/ble-stack-3.x/stack-configuration.html#stack-configurations, but wanted to ask if there are other relevant features).

Thanks!

Hi,

CC2640R2F support Bluetooth 5 Low Energy PHY features. So you can get your information in Bluetooth 5 PHY (ti.com), since 2640 does not support sysconfig, you may need to modify in code.

Best regards

Hi, Simon! Thanks for the response.

In this case, we are using the standard BLE-Stack (only 4.2 features) -- not the BLE-5 Stack as referenced. I also noticed the link did not include information regarding the adjustment of transmit power, etc.

My question for the BLE-Stack... which particular settings must be the same between "host_test" and my custom project for the purposes of qualification (SIG and FCC) testing?

Thanks!

1-I understood, I gave that BLE5 link because the PHY are same here.

2-please review Configuring the CC2640 for Bluetooth® Direct Test Mode (ti.com) and PTM cc2640 - Texas Instruments Wiki (ti.com)

Thanks for the references, Simon!

I looked over the documents you referenced (the second link appeared to be broken, but I did find this - link). I guess my question is more nuanced than how to setup DTM or PTM (I have been able to run DTM on our product using the host_test project).

In particular, I am wondering which BLE parameters may impact RF-PHY operation for the purposes of qualification... either hard-coded parameters (e.g., in ble_user_config.h/c) or run-time parameters configured through the GAP/GATT/HCI APIs (e.g., in section 5.7 of SWRU393e).

Would a next step be for me to read through some of the API commands in SWRU393e?

Thanks again!

Hi,

Sorry for the late response. I thought I answered yesterday but it seems not sent.

All the BT RF PHY parameters are covered by device characterization and data sheet performance numbers. So please use hard-coded parameters if you are doing qualification. We also have related files, I'll attach them later today.

Thanks, Simon! When you refer to the datasheet, do you mean SWRS204C? I did not see any particular software parameters mentioned in that document, but will await your files. Thanks again for your help!

Here is the file. I am sorry for the same problem happening again. I replied but nothing is shown in this page. next time I'll make sure my answer is published.

Thanks, Simon! According to the guide, the host_test project can be used for RF-PHY testing assuming the "protocol stack and radio configuration" are identical between it and my custom project.

"protocol stack" -- I assume this is the underlying SDK (i.e., "simplelink_cc2640r2_sdk_5_30_00_03") -- is that correct?
"radio configuration" -- what is entailed in the radio configuration? Are these the software settings configured via HCI and/or RF commands?
