DS18B20 Sketch from Examples doesn't brings Node to sleep.



  • Hi, the 1.1 Sketch doesn't brings the Node to sleep with 2.0.1-beta.
    Anyone else is having this problem?

    I have two nodes and both having this issue :(

    What type of hardware?



  • Arduino Pro Mini with NRF24L01+...

    It Works great with the "old" 2.0.0 beta.



  • Any Ideas, why it is not working with new 2.0.1-beta?

    Could you post more infos plz ?

    • your sketch even if it's the original
    • which lib you're using for onewire
    • enable MY_DEBUG in sketch and post the logs

     * network topology allowing messages to be routed to nodes.

    @Floca Your node is defined as repeater, and repeaters do not sleep by definition:

    See log:

    65890 !MCO:SLP:REP
    

    To disable repeater mode, comment this line (writing "Disabled" won't work):

    #define MY_REPEATER_FEATURE Disabled
