nRF52 shows "unknown function at 0x00000A60" after 58 minute fix time

[Nik.P]

Hello Nordic Community,

I am using nRF52840 SDK 17.0.2.

I took examples\ble_peripheral\ble_app_beacon as reference and created mBeacon profile.

Then I created three different handler using timer.

First is beacon timer handler which starts advertising at every 20 second.

Second is sampling timer handler which occurs at every 60 second period and measures sensor values also updates these values in advertising.

Third is logging timer handler which logs sensor data on UART at every 60 second time period.

everything is working continuously for 58 minutes after that it shows "unknown function at 0x00000A60".

I haven't used and debug point in code. Debug is used for RTT logs only.

Can you tell me what is wrong going here?

Thanks in advance

Nikunj P.

Hello Einar,

After debugging I found that after commenting some part code works for longer time. I sent you private message of code can you look at it and find any memory leak for me?

Thanks,

Nikunj

Hi Nikunj,

I looked though the code again and I am still not able to pinpoint what causes the issue. I do not have knowledge about all the external code you use though, so that might be related. Aare you able to comment out even more to narrow down the issue even further?
