    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```

              @rmtucker

              Please can someone update the instructions below to mention installing the development version

              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.

                      @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.

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

                                    I2C should be fixed now. Version 0.4.0 is released!

                                    To help clarify for others who are reading this: the Arduino IDE board manager let me upgrade to 0.4.0 from 0.3.0 by just clicking on the board entry "Nordic Semiconductor NRF5 Boards by Sandeep Mistry", selecting the 0.4.0 version, and then clicking Install.

                                      1. I have updated the radio driver with fixes for some hardware errata.
                                      2. I have updated the https://github.com/mysensors/ArduinoHwNRF5 with an enhanced definition format. File name and contents are changed! The board description is compatible with the NRF5 variant provided by Arduino, but it's not possible to use this variant at the moment.

                                        Where do we find the update? i.e. is it baked into the regular MySensors development code thread, or is it elsewhere?

                                          I'm guessing it's this one? https://github.com/mysensors/ArduinoHwNRF5
