RE: Peripheral stops notifying data after working for some hours, then get backs to work in an hour

Hi,

I figure out why it's not working. It's because one of my thread was getting an infinite loop, causing the thread hang up. After a while, CPU locks up triggering the reset.

Thanks.

Hi!

1) Do you have any logs from the device?

2) Does e.g. the function you call to send notifications return any errors?

3) Have you confirmed that the function you use to send notifications is actually being called? e.g. either through UART log-output, or e.g. toggling a debug pin

4) Maybe the central turned disabled the CCCD for the notifications, or that the notifications are actually sent over-the-air but not reported to the phone application. To see what's happening on-air, could you capture a sniffer trace of the issue? https://www.nordicsemi.com/Products/Development-tools/nrf-sniffer-for-bluetooth-le
