S120 2.1.0 - system reset when connection to S110 is lost

[woytekm]

Hello, are there some known reasons why S120 can reset the system while BLE connection to S110 peer is lost? I have S120 and two S110 connected. When i take one of S110's out of range of S120, in my RTT debug console (via JLinkRTTClient) i see that my S120 simply reloaded itself when connection with S110 (one moved out of the range) was lost... (S120 is 2.1.0, both S110's are 8.0.0). No BLE events are generated just before S110 disconnection and system reset... What could potentially cause such behavior?

Thanks, Wojtek

Can you describe the code you are running? Is it an SDK example?

Read this post about error handling in the SDK, and tell us about what you find.

Hi Anders, you were right - reload was caused by APP_ERROR_CHECK. Indeed i am using one of example programs as a skeleton of my application, never actually bothered to check what APP_ERROR_CHECK does, and left it in few places in the code as it was in the example app. I need to implement my own error handling.
