Hello! I have a problem when scanning and advertising at the same time with a NRF51822 and S130 v.2.0.0. (SDK11).
I can start both scanning and advertising without any problem and they seem to work fine, but the problem is that if I do both at the same time the device gets stuck at random times at the following code in the stack and triggers a watchdog timeout due to this.
Assembly output of where it gets stuck and loops:
00014184: wfe
00014186: ldrb r0, [r4, #20]
00014188: bl 0x10c9a
0001418c: cmp r0, #0
0001418e: beq.n 0x14184
As a test I've setup my device to run scan and advertisement directly from start with short timeouts. 2 sec scan, 5 sec advertisement and when done it repeats this procedure. With this the problem triggers at random times within 1-30 minutes from system start. (Note: times chosen close to what I need for my application).
I've tested to run both advertisement and scanning independently and it doesn't trigger the problem when I do this.
Advertisement interval is set to 100 ms. Scan interval is set to 50 ms and window is set to 25 ms. Watchdog set to 2 seconds timeout.
Has anyone else encountered the same/similar problem or could someone from Nordic give a hint to what the code in question is doing/waiting for?
