@scalz ohh! Where can I order one?

@heinzv I'm sorry if I was unclear. I have only updated and tested one example which is the PCA10059 It should build without errors, but you might need to specify build type as "ble" or "dongle" as per the readme.

To enable the NRF52840 support use these flags:

-DNRF52 -DNRF52840 -DNRF52840_XXAA

and if building with the BLE Peripheral library and Softdevice S140 add:

-DNRF52 -DNRF52840 -DNRF52840_XXAA -DNRF52_S140

@heinzv

1. 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.

2. 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

1. Linux environment example, first build the PCA10059 example project:

pio run -e ble

1. 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

1. 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

... and Bob's your uncle

@NeverDie I never liked the Arduino IDE, so I think PlatformIO is next logical step, it is very easy to get going and it opens up for advanced usage. Your own choice of editor, has great debugging capabilities with VSCode integration.

If you build the PCA10059 example I linked you should have GPIO (digital) access to all 47 pins. I've made it simple in the pca10059 variant so that D0 (0) is p0.00 -> D47 (47) is p1.15.

Some external pins on the dongle which I have tested:
Serial pins RX->P1.10, TX->P1.13
I2C, TWIM, Wire on pins CLK->P0.29, SDA->P0.31
SPI here MISO->P0.13, MOSI->P0.15, CLK->P0.17, CS->P0.22

Big thanks to @sandeepmistry, @lpercifield, @jeremypoulter and all others contributing to the NRF Arduino development effort. I have borrowed a lot and forked off another project for adding support for the NRF52840 dongle (PCA10059). If you are using PlatformIO and have access to a NRF52840 you can take it for a spin here PCA10059. I have tested UART, TWIM, SPIM and the BLE Led toggle example works.

@jerseyguy1996

You'll need a Controller to update the firmware in the nodes. I'm using MyController.org running on a RPI3 with a MySensors serial Gateway. Works great!

Shall we all join hands and give a warm applause to @tekka for his work and pray that he'll find the time to give us a lovely christmas present. The MYSBootloader 1.3+ pushed to github

@tekka

Finally some action here again! Yeah!
Any chance we can get our hands on the source so that we can change channels/power and finetune led status and such?

@tekka

Quickly checked the code on 1.1 and it doesn't seem to support normal serial upload?
It would be great if you could publish 1.3 or 1.4 so people can make use of your efforts until you find the time to finalize it?

///Rickard

Ohh. I'm also very eager to have my hands on the source of the beta. Please share so that we can help finalize it. I have a bunch of sensors ready for deployment, but I need a bootloader that can upgrade them. Since software is never ready

///Redferne

Is there any development of this plugin?

Hi,
Will you update the SampleController for the new bootloader or the protocol unchanged?
I need a solution to push firmware updates from a Linux machine through a serialgateway to all nodes.

I'm happy to test and share my experiences.

@Mayank-Raichura I had the same problem with usbasp. The fix was to remove the -D flag (disable auto erase) when running avrdude.
