MySensors needs restart to communicate

  • I have updated MySensors to 2.2.0 on my RPi two weeks ago. Clean new install. If I try to connect from a node, I get error messages, as long as I do not restart the MySensors gateway. MySensors Libary on Arduino IDE is also 2.2.0, all sketches are updated.

    2125 TSF:MSG:SEND,20-20-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK:
    4135 TSM:FPAR

    On the RPi MySensors runs atm in debug mode - I can not see any incoming communication. As soon as mysgw is restarted (kill process, then mysgw -d), mostly the node gets the connection and runs fine (without restart). As soon as I restart the node (soft reset or sketch update), there´s again no way it connects.

    Tested with several notes and sketches, also example sketches from the page.

    are you sure the process is running? can you connect to the gateway using a controller?

    Thanks for your reply 🙂
    It seems it is the antenna on intialisation. I have switched form NRF24 with antenna as print on PCB to the ones with external antenna, plan was to have more range. Always supported by a 470μF condensator.
    If I put my finger on top of the antenna while it initializes, I have a stable connection without restart of the gateway. From there on, I do not have to touch it anymore, communication runs perfect. If I do not touch the antenna, I have only errors until I restart the gateway on the RPI (restarting the node does not have an effect).
    Btw , antennas were 20cm, then 3m away from each other, nothing in between

    Cheap clones are often a pain. Look on the store links on, the most expensive ones are the ones I have and work perfectly with my rpi3
