Configurations

nsh

Basic NuttShell configuration (console enabled in UART0, exposed via USB connection, at 115200 bps).

sdc

Enables Nordic’s SoftDevice controller and uses nimBLE for the host-layer. The nimble test application can be used to enable a simple GATT server.

Flash & Debug

Both flashing and debugging are done using the embedded DAPlink debugger. OpenOCD can be invoked in the following way to flash:

openocd -f interface/cmsis-dap.cfg -f target/nrf52.cfg -c "program nuttx/nuttx.bin 0x0000000 verify reset; shutdown"
