    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.

    @rmtucker can't you just bit bang the I2C sensors? Should not be any mcu incapable of that. There should be plenty drivers available that implement a bit banged I2C driver.

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

      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.

        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.

              Yes They are 3.3v sensors.
              What we need is someone else using nrf51822 and i2c sensors that can shine some light.

                I'll try soon, hopefully I'll have time tomorrow, my nrf51 module is soldered on a breadboard. I need to make the promised tests on the nrf52 too ...

                  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.

                    Well guys after all that :frowning:
                    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```

                          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.

                              @scalz: I think @rmtucker was discussing using the development version of the sandeepmistry nrf5 Arduino library, it was not related to the MySensors library.

                                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 menu
                                

                                Following 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 IDE
                                

                                Otherwise 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.

                                        If this don't work, remove all folder created by hardware and boards manager, close Arduino IDE and reinstall it via Boards Manager.
