Hello,
im trying to send Data from one Devkit to another (nrf9160 from nrf52840) the Problem is that if i enable Bluetooth on the nRF52 i get an error when receving/transmitting Data via UART.
The Error Code is (RTT LOG of NRF52):
00> [00:00:11.234,375] <inf> app_uart: Received data len:1 bytes,offset:0
00>
00> [00:00:11.234,771] <inf> cmd: Length Rec: 1
00> ASSERTION FAIL [!arch_is_in_isr()] @ WEST_TOPDIR/zephyr/kernel/mutex.c:101

00> [00:00:11.258,300] [1;31m<err> fatal_error: Resetting system
As far as my Code is concerned i dont use extra Threads or Mutexes in the Uart Code.
My Code for both Kits is Zipped here:
nRF91ichip.rar
nRF52bchip.rar
As you can tell im trying to Implement a Cross DFU via Uart.
Any possible Solutions or Ideas would be greatly appreceated
