Product crash with nrf51822 peripheral s130 2.0.1 : how to get logs or more information ?

Dear Mr/Mrs,

Our commercialized product currently have a default: some (luckily rare) clients get a crash after the 1st configuration - sometimes hours after but always while being connected. The product is totally blocked, and need a hard reset to work again. After the reset, it seems there is no problem any more.

It's very difficult to reproduce in our side. Our hypothesis on the crash goes from a (rare) stack size issue to a cold start specific one. It could also be an unwanted bonding.

Anyway, is there a way to get some interesting logs from the softdevice ? (as there seems to be no more BLE activity after the crash, we guess that it happens at the softdevice level, not in the application side). NRF logs (using uart) returns only assert and softdevice configuration issues from the sdk, as far as I can see.

And if you have any suggestions or ideas to get more information about this crash...it would be much appreciated !

Best regards,

Julien
