nRF5 action!
-
@neverdie read Issues section in Mark Cooks's repo referenced above. He's just committed a PR to support the display.
I need nrf52 to able to use Central role in my projects. For Mysensors nrf51 is pretty adequate if someone wants to create something like a wearable weather station :-)
Everything is in place. -
Note: to hack it you need a J-Link device:

So I made a version of script with MySensors library, it's not a final version and needs some cleaning and improvements but it seems to work well (I didn't test so much yet :)) and shows basic usage. Comments should be enough to understand what to change to adapt to your board. Current script is for my board:
- BUTTON_1 on pin 1, it's a hall sensor for door so no pullup and sensing on up=>down and down=>up changes
- BUTTON_2 on pin 3, push button with pullup and debouncing, sensing only on up=>down when button is pressed. At the moment it just makes some light blinking to show it's detected.
- led on pin 2.
I join the main script file and the MyBoardNRF5 files, for using with MyBoardNRF5 nrf51822. Files to include are described in the main script file, but don't forget to add a weak attribute in the WInterrupt.c file before the GPIOTE_IRQHandler so it can be overridden.
__attribute__ ((weak)) void GPIOTE_IRQHandler()On my Windows PC this file is in C:\Users[your user name]\AppData\Local\Arduino15\packages\sandeepmistry\hardware\nRF5\0.5.1\cores\nRF5

This file was part of the "My Sensors nRF5 Boards" board repository available at https://github.com/mysensors/ArduinoBoards If you have questions, please refer the documentation at https://github.com/mysensors/ArduinoHwNRF5 first. This file is compatible with ArduinoHwNRF5 >= 0.2.0 This file allows you to change the relation between pins referenced in the Arduino IDE (0..31) and pins of the nRF5 MCU (P0.00..P0.31). If you can live with addressing the GPIO pins by using the Arduino pins 0..31 instead of a custom mapping, don't change this file. If you have a lot of Arduino code with fixed pin numbers and you need to map these pins to specific pins of the nRF5 MCU; you need to change this file. If you fill the "g_APinDescription" Array with numbers between 0..31, the Arduino pins 0..31 are assigned to pins P0.00..P0.31 of the MCU. As an example, if you need to change the pin mapping for Arduino pin 5 to P0.12 of the MCU, you have to write the 12 after PORT0 into the sixth position in the "g_APinDescription" Array. The extended attributes only affects the nRF5 variants provided with official Arduino boards. The arduino-nrf5 variant ignores the extended attributes. The pin mapping effects commands like "pinMode()", "digitalWrite()", "analogRead()" and "analogWrite()". If you change the pin mapping, you have to modify the pins in "MyBoardNRF5.h". Especially the analog pin mapping must be replaced with your pin numbers by replacing PIN_AIN0..7 with a number of your mapping array. You can use the constants PIN_AIN0..7 in the "g_APinDescription" Array if you want to reference analog ports MCU independent. You cannot use the pins P0.00 and P0.01 for GPIO, when the 32kHz crystal is connected. ########################################################################### Copyright (c) 2014-2015 Arduino LLC.

@alowhum there is a whole "movement" of people who are trying to reprogram them. Key issue is openability (how hard is to open it)
The last easily openable watches are based on nrf51822, but the good thing is that programming pins are easily accesable and even marked SWD/SCLCK.
Search Ali for ID107HR and google for "roger clark smartwatch"
I am yet to find a watch that would be both nrf52 based AND easily openable@toyman said in nRF5 Bluetooth action!:

Just curious design consideration, based on my question to Nordic:
https://devzone.nordicsemi.com/f/nordic-q-a/33448/led-power
LED consumption will not exceed 0.5ma if the pin is configured as s0s1
@toyman Maybe that's enough to light a subset of the pixels on the display?
In theory these nRF52832 BLE are OTA re-programmable. If someone left the door open for that, then you wouldn't have to crack the case or fight with the glue. Well, maybe someday...

@neverdie I was thinking about that, but that's not gonna work. Why? The bootloader that accepts OTA has a private key. The key in the software should match the key.
@toyman Would this work? Buy two. Sacrifice the first so that you can image the firmware on the chip and extract the password. Use that password to unlock the OTA firmware update for the second one.
Or, maybe it's the universal bluetooth password: 1234. Maybe try that first. ;)

afaik mysensors nrf52 isn't working with softdevice yet (same as your 'bootloader' here). there might be some conflicts with nrf52 resources (timers etc.). so you may need to open it for reprogramming.

For me losing Bluetooth would be a feature: it makes you less likely to be tracked while in stores / smart cities.

I turned a ST-Link v2 into a Black Magic Probe using this guide.
The Black Magic Probe creates two virtual serial ports. One to program over, and another one. Can that second one be used to listen to Serial output from the NRF52? If so, how can that be set up?

@alowhum I'm using a BMP that I made from a STM32 Blue Pill. The Serial works just fine.
Set a TX pin on your NRF5 in the MyBoardNFR5.h file. Connect it to the RX pin on your BMP. The default pins are TX (PA.2) and RX (PA.3). So if you connect PA.3 on your programmer to the TX pin you select on the NRF5, you should have what you need.
To program, select the lower number serial port.
To see serial output, select the higher number serial port for your serial monitor. -
@nagelc I am using a ST-Link V2 that I turned into a BMP. So i don't have a RX pin on that. But I do have these pins left:
- RST
- SWIM
So you suppose any of these two pins are now RX?

@toyman Looks like a DIY watch, using one of the very small nRF52 modules and a small OLED screen (or maybe ePaper?) would be fairly easy to design and put together.

Still, maybe a DIY bridge would tide you over until a more proper watch is available for conversion. Interestingly, it looks like they made their case from stacked pieces of laser cut acrylic.
Unfortunately, theirs is impractically large:

@alowhum Reset seems unlikely. Maybe SWIM. You could try it.
If you can follow the trace back to the microprocessor, then you could figure out which pin it is. Then you could change to that pin in the BMP files, recompile, reload . . .. . Not sure it's worth all that experimentation when you can just use an FTDI as @NeverDie does.
