Com.X.LoraWan 868 module configured at 470Mhz ?



  • HI All,
    just bought the module COM.LoRaWAN 868 and I'm trying to configuring as Lora to test communication with a different module i got.
    When i try to configure the frequency, I got error "+ERROR: the command is not supported"
    I'm trying with:

    • ATCommand("FREQ", "868000000");
    • ATCommand("LoraPara", "868000000,18,12,0,1,8,1,0,0");
      and I get the same error.
      Then I tried to inquire about current setting and I get on reset::

    16:21:56.550 -> AT Rev 1.3
    16:21:56.550 -> +AutoLPM=0
    16:21:56.550 ->
    16:21:56.550 -> +LORAWAN=0
    16:21:56.550 ->
    16:21:56.550 -> +FREQ=470000000
    16:21:56.550 -> +TxPower=10
    16:21:56.550 -> +SF=7
    16:21:56.550 -> +BW=0
    16:21:56.550 -> +Coderate=1
    16:21:56.550 -> +Preamblelth=8
    16:21:56.550 -> +CRC=1
    16:21:56.550 -> +IQInvert=0

    and by issuing " ATCommand("LoraSet", "?");"
    16:21:59.708 -> +LoraPara:470000000,10,7,0,1,8,1,0

    If i check on the chip CubeCell, below the logo it show 863-870
    Is there anything wrong on my module?



  • Hello @ecasti

    no, I don't think there is anything wrong with your module. My two modules report the same firmware version 1.3 as yours and the same frequency (470000000) is returned when uninitialized. I also get the same error (not supported) when trying to set the frequency via FREQ. I think the documentation doesn't 100% match the firmware installed on the module.

    I am using below command to setup LoRa parameters for a point to point connection:

      ATCommand("LoraSet", "868000000,18,12,0,1,8,1,0,0");
    

    Thanks

    Thanks a lot, Felix,
    it works !
    Will try to find more details about this firmware to drop some note here.
    Happy New Year
