cyw20719b2 SDS Sleep with TRASNPORT / NO_TRANSPORT hard reset

[anje_2248446]

Hello Cypress,

I have cyw20719b2 SDS Sleep configuration with TRASNPORT / NO_TRANSPORT mode. Device goes to SDS Sleep correctly. But after around 3 minutes in SDS Sleep device gets hard/cold reset, this issue is observed if BLE Advertising is turned off just before allowing SDS Sleep. If BLE Advertising is not turned off, then issue is not observed and device stays in SDS Sleep until there is a wake up triggered from gpio interrupt.

BLE advertising interval is set to infinite (set to 0).

I just want to confirm if it's possible to keep ble advertising off in SDS Sleep ? OR it is mandatory to keep ble advertising on when device is put in SDS Sleep ?

Thanks,

Aniket Jesu

Hi Aniket Jesu,

I can see that this issue is internally fixed, but the fix is still not available in the latest SDK because it needs more internal testing from our validation team. Hopefully, the fix will be available in the next SDK.
