CC2340R5: basic_ble crashes using static random address

Shuyang Zhong

Part Number: CC2340R5
Other Parts Discussed in Thread: SYSCONFIG

I am trying to change the address type to static random address, but after the modification the basic_ble example did not work anymore. The program never enters App_StackInitDoneHandler() after executing vTaskStartScheduler().

I have noticed an invalid random address can cause the BLE stack to crash on CC26x2, so I tried with two different addresses which I believe both were valid: C0:11:00:11:00:11 and CA:00:00:00:00:CA, both did not work.

Please help confirm if this is a bug in the stack, thanks!

Hi Shuyang,

I am afraid the addresses you are mentioning are not valid Random addresses.

Can you please check with C0:11:00:11:00:13 and CA:00:00:00:00:CF?

Best regards,

Hi Clement,

I tried both of the addresses and they did not work neither. Can you please help verify?

Hi Shuyang,

I am not sure which device you are currently using. Can you specify this information?

Also, can you please verify with CF:00:00:00:00:CF?

Hi Clement,

It is not because of the address, but because the generated random address by sysconfig is not passed to the appMainParams struct.

Adding .pDeviceRandomAddress = pRandomAddress to appMainParams struct in app_main.c will fix this:

I suppose this is a bug in the stack, would you please help file a ticket to fix this? Since CC2340 does not support a secondary BLE address in CCFG, customers are using the random address to specify the address of their products, this could impact other customers as well.
