Part Number: CC2541
Other Parts Discussed in Thread: BLE-STACK

I have a problem with my custom board.

After a long run, my CC2541 stop to advertise itself or cut the connection if I'm connected to it.

The problem is my software don't see the problem and continue to work as usual.

I attached the radio registers values BEFORE and AFTER the bug.

Someone can tell me if something sound strange in the values ?

I need information on :

- What can be the root cause.

- or how to detect the bug in the software.

I paid attention to register RFFSTATUS but not sure it give me information on the root cause.

Thanks

This was addressed in BLE-Stack 1.4.1. We recommend upgrading but you could try increasing the HAL_SLEEP_ADJ_TICKS until the problem is no longer observed.

Sorry JXS,

my version was 1.4.1 ...

I increased the HAL_SLEEP_ADJ_TICKS (to 80 instead of 55) and now I'm checking.

Anyway, do you have a good way to detect this issue in the SW ? (like checking the registers, which ones, etc ...) ?

Did you see something strange in the registers values I posted ?

Maybe a work around can be enough to fix the issue, but of course I need my code to detect that.

Thanks
