nrf24L01+ 1715AH versus 1452AB problem



  • I have two sets of nearly the same modules. The only visible difference is this number above. The modules with chip NRF M, 24L01, 1452AB work without problem. The modules with chip NRF M, 24L01, 1715AH did not. I tested 5 new modules from each series with the same node hardware and software.

    Here the protocol of the not working 1715AH:

    0 MCO:BGN:INIT NODE,CP=RNNNA--,VER=2.1.1
    3 MCO:BGN:BFR
    BEFORE...
    5 TSM:INIT
    6 TSF:WUR:MS=0
    13 TSM:INIT:TSP OK
    15 TSM:INIT:STATID=50
    17 TSF:SID:OK,ID=50

    8201 TSM:FAIL:CNT=1
    8203 TSM:FAIL:PDT
    

    Hope someone can help. I saw a lot of topics concerning those modules on this forum but as a non-expert it is difficult to find the right answer.

  • Mod

    Usually it is most likely a bad Chinese clone. You can't do much about it, just get the genuine ones.

    But how can I be sure to get the genuine ones?


  • Mod

    There are a couple of open topics. Search for "genuine" and "counterfeit"



  • Thanks, but that is too much discussion for me. Can't someone simply answer with some links where to buy genuine modules for sure or where someone recently bought some which works?


  • Mod

    @Heizelmann no. That's why the discussions are so long.


  • Mod

    That is also a reason why I am moving to RFM69 as at the moment it looks there are no fake modules around.
