NRF52 Auto Reset

[Nguyen Trong Tuan]

Hi everyone,

I'm programming nRF52833 for my application. In my application, I used ble_advdata_parse to read the advertising packet for filtering mine device. However, The systems only run for few seconds and then it reset by itself. When I debug I got some messages like this. Here is my code. Can anyone tell me some ways to figures it out?? Please reply as soon as possible!!!

Thanks

Best regards!!

Hi,

It looks like one of the functions in ble_evt_handler() is returning the NRF_ERROR_INVALID_STATE(8) error. I can't tell  which one based on the image of the callstack you posted. However, the debug logs from the default error handler (Error module) should include that information. If this is based on an SDK project you should be able to enable logging over RTT simply by applying the following configurations to sdk_config.h

NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED 0
NRF_LOG_BACKEND_RTT_ENABLED 1

And make sure you also select the "Debug" configuration before you debug. This will make the crashlog include the file name and line number of where the error occured..

Here is where the error comes from. Sr I can't follow your Instruction. There are many error when I change things like what you said because I used FREERTOS for my application so it's seems like I have some troubles to handle with if I change like that.

Where is the error coming from?

 Are you able to upload your project here or in a private support ticket so I can take a look?

Edit: For some reason I didn't see the screenshot you posted earlier. Anyway, it seems like the error is returned by sd_ble_gap_disconnect() in the  BLE_GATTS_EVT_TIMEOUT event, which indicates that the device was already disconnected when this event got processed.
