there are quite a few that have the same problem.
Yes, the ones I noticed that seem to have the problem are: motion, smoke, dimmer, cover, scene controller, and, of course, multimeter. The rest compiled.
I don't know the answers to your other good questions, but AFAIK @d00616 appears to be the point man. Perhaps @d00616 can comment?
Also, if you're not already aware of it, @rmtucker I invite you to join in on the constantly evolving discussion at: https://forum.mysensors.org/topic/6961/nrf5-bluetooth-action/498
@NeverDie
Just wondering about mysensors debug.
If you have the jlink plugged in for programming but you also want to see the mysensors debug.
Where is the ftdi adapter plugged in to for tx and rx ?
And also i suspect that the vcc is not connected on the ftdi adapter because the jlink is supplying the board?
Oh so many questions?? -

That's determined by the "board" that you tell the compiler you are using. For example, on the nRF52 DK, the Rx pin is on P0.06. Presently, for simplicity, when I compile for the Ebyte module, I tell the Arduino IDE that it's an nRF52 DK, so then Rx is also on P0.06 and Tx is on P0.08.
A more advanced way of doing it is to tell the Arduino IDE that the board is a "MyNrf5Board nRF52832", and then you can use d00616's method of pin mapping to make the Rx pin whichever of the mappable pins you want. That's a bit more involved though.And also i suspect that the vcc is not connected on the ftdi adapter because the jlink is supplying the board?
Right. For old fashioned debugging using serial.println(), just Rx and GND is all I use.

@NeverDie
Disappointed so far with the NRF51822.:frowning:
Basically it can not connect to any i2c sensors which mysensors relies on heavily.
So not a lot can be done with it.
It does integrate with mysensors well though,proved that with mockmysensors sketch.
I dare not even try the spi interface.
I would advise not trying this till the i2c problems are sorted out.
At the moment it is running Blinky and thats it. -

Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

@Anticimex
I managed to get a nokia 5110 display connected and working using the u8glib and softspi.
I can not get the easier to use adafruit library to compile though.
Nor have i been able to find a Soft i2c library that will compile without errors.
So i am afraid i2c is still a non starter. -
@rmtucker said in 💬 MySensors NRF5 Platform:

maybe try this one https://github.com/felias-fogg/SlowSoftWire
I don't use it, but it compiles fine for nrf52. I already tested it a while ago, and it worked for me. -

my head is battered with this.
tried the library you mentioned and it compiled fine but still gave spurious readings.
so i plugged the htu21d back in to a nano and used the sparkfun library demo.
the readings were perfect.
so frustrated with this because all my nodes use i2c sensors. -

Stupid question, but are your i2c sensors getting all the voltage that they need? After all, a nano runs at 5v, right? I know that some of the TH i2c sensors include voltage regulators, which would drop the voltage even further. If necessary, those could be removed. That's what I generally do. -

@NeverDie
Yes They are 3.3v sensors.
What we need is someone else using nrf51822 and i2c sensors that can shine some light.@rmtucker said in 💬 MySensors NRF5 Platform:

@Nca78
Just an observation after many hours of tinkering.
There is no problem reading one byte back from i2c,like when doing an i2c scan.
It comes back with the address of the htu21d no problem.
But if you try to read 3 bytes which is what you do when reading the temp etc,it goes T*TS up. -

I had not installed the development version from git.:angry:
After installling the development version the i2c is working fine.
Suprised no one else has done this??From git (for core development) Follow steps from Board Manager section above cd <SKETCHBOOK>, where <SKETCHBOOK> is your Arduino Sketch folder: OS X: ~/Documents/Arduino Linux: ~/Arduino Windows: ~/Documents/Arduino Create a folder named hardware, if it does not exist, and change directories to it Clone this repo: git clone https://github.com/sandeepmistry/arduino-nRF5.git sandeepmistry/nRF5 Restart the Arduino IDE``` -

Preparing Arduino Arduino doesn't support the nRF5 platform in a standard setup. You have to add the arduino-nRF5 platform via Arduino's Board Manager like described in https://github.com/sandeepmistry/arduino-nRF5/#installing -

If there are multiple libraries with the same name (as there seem to be), then how does the compiler know which one to pick? Is it just the first one whose name matches in whatever pathway it follows? Since it obviously compiled even though rmtucker was missing the proper libraries... this just sounds like a heartache waiting to happen unless everything is setup just-so. rmtucker's case seems to prove there won't be any warnings if it picks the wrong one.

looking at d00616 howto it's explained to use Mysensors development branch (or maybe he added it today :) ). but that makes sense as this port is newer than master branch.
@NeverDie
it uses the core libraries depending on the board used in Arduino. -

@mfalkvidd
Sorry i should have made it more understandable.
When you follow the instructions below as per sandeeps site it does not install the latest NR5 libraries that you see on github.Installing Board Manager Download and install the Arduino IDE (At least v1.6.12) Start the Arduino IDE Go into Preferences Add https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json as an "Additional Board Manager URL" Open the Boards Manager from the Tools -> Board menu and install "Nordic Semiconductor nRF5 Boards" Select your nRF5 board from the Tools -> Board menuFollowing this you must install the development version aswell which is what you see on github by doing this.
From git (for core development) Follow steps from Board Manager section above cd <SKETCHBOOK>, where <SKETCHBOOK> is your Arduino Sketch folder: OS X: ~/Documents/Arduino Linux: ~/Arduino Windows: ~/Documents/Arduino Create a folder named hardware, if it does not exist, and change directories to it Clone this repo: git clone https://github.com/sandeepmistry/arduino-nRF5.git sandeepmistry/nRF5 Restart the Arduino IDEOtherwise you run into all kinds of problems using the old library.

I have added a note at the end of the installation documentation. To make things easier, I have opened an issue to update the Arduino-nRF5 release.

I2C should be fixed now. Version 0.4.0 is released!
