It does use the S140 v6.1.0 Softdevice, however I have only "ported"/test the most basic SDK 15.2 BLE feature of @sandeepmistry BLEPheriphal BLEPeripheral. The example shows as BLEService and Read/Writeable BLECharCharacteristic used to toggling the onboard LED. I was hoping we could get more developers involved and "port" the missing pieces, if there's interrest. My main focus was just to get something Arduino-like running using PlatformIO build system on the cheap (~$10) NRF52840 dongle.
I have tested Black Magic Probe (Bluepill) and JLink Mini on the PCA10059 with great success. It also possible to use the nrfutil to create a dfu.zip. The Nordic Open DFU Bootloader (which is pre-flashed on PCA10059) allows easy programming without soldering, just plug-in USB.
First get and install the nrfutil from here
- Linux environment example, first build the PCA10059 example project:
pio run -e ble
- Generate a dfu.zip including the softdevice:
nrfutil pkg generate --hw-version 52 --debug-mode --sd-req 0x00 --sd-id 0xAE --application .pioenvs/ble/userfirmware.hex --softdevice ~/.platformio/packages/framework-arduinonordicnrf5/cores/nRF5/SDK/components/softdevice/s140/hex/s140_nrf52_6.1.0_softdevice.hex dfu.zip
- Plugin the PCA10059 dongle in a USB port. Make sure that the Bootloader is executing by checking the RED led, should be "breathing". Else press the reset button. Now flash the new firmware, here the dongle was enumerated as ACM3.
nrfutil dfu usb-serial --package dfu.zip --port /dev/ttyACM3
