Radio stops working



  • Hello,
    (arduino + NRF24L01+)
    I have a node which only works in reception.
    Its role is to control a 220Vac power relay.
    A few times when the relay is switched, i think the radio stops working (certainly due to electromagnetic disturbance).
    From this moment the arduino sketch still works but the node no longer responds to the gateway.

    How to make the node detect this radio problem ?
    How do I get my sketch to do a cold restart of the radio ?

    Thanks for your help.

    I don't think there is a function to do this, but maybe someone else can help with that.

    It would be good to see how you wired this all up - a hand drawn sketch or fritzing would do. I suspect that by modifying the way power is applied may need arjusting and come capacitors may need adding - You can reboot by using a hardware watchdog circuit (web search for it).
