nrfErr = sd_ble_opt_get...
Problem:
We trigger HardFaults reproducibly. By manually unwinding the stack we have traced the source of the error back to the TIMER2_IRQHandler in Gazell.
We can see...
Hello,
I am using SDk 11.0.0 and I am trying to integrate the DFU from the heart rate example into the my code, which is based upon the BLE UART (NUS) example. When I run...
