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"
|
|
|
