    • RE: Lora 868 module external antenna

      Hi,

      Sometimes I find IPX (or I-PEX or U.FL?), sometimes MCX, sometimes SMA... on descriptions

      So I link them all here... so you can find out yourself

      SMA wikipedia the most common one, it is threaded

      MCX wikipedia snap in

      IPX I-PEX U.FL wikipedia very tiny, mostly used on little pc board connections, surface mounted, snap on

      For antennas, you could do an internet search with keywords: "868 MHz antenna"

      Also YouTube is a nice source for searching all these terms

      LoRa module video on YouTube at 2:00 minutes it shows internally U.FL connectors, and externally MCX if I am not mistaken

    • RE: Lora Module ASR6501 with Arduino

      @sasoo The code by christianc is incomplete and does not work

      The AT+CRX and AT+CTX are test commands, not meant for this application, and take your asr6501 in a dead loop, see documentation

      When doing this with an antenna connected, you might transmit without knowing you do, and cause interference for others

      In fact it seems Peer to Peer LoRa with asr6501 is not possible, it is designed for only LoRaWan, if I am not mistaken...

      from documentation:
      Notice, When enter into CTX Test, system enter into dead-loop, if you need other test then reboot the board for the next other test command.

    • RE: COM.X LORAWAN 915 AT+CRXP=0,0,923300000\r\n command error with m5stack fire

      @sippanan_p

      It seems that your band frequency is OK for US, so do not worry about setting the RX window?

      Maybe not able to join has another cause?
