I was looking forward to playing around with these and maybe creating a point to point network of sorts. Just to play with, maybe transmit weather data. I don't seem to get any response with the module though. I was following the <a href="https://www.hackster.io/sodoku/m5stack-com-lorawan-using-uiflow-fdcd7f" target="_blank" rel="noopener noreferrer nofollow ugc">M5Stack Tutorial</a> with the Grey Core. I have everything as shown in the picture in the tutorial as far as RX/TX pins. I get no response at all in the M5 Burner, but if I open the serial monitor in the Arduino IDE, I get the following ERROR. Any ideas where to start? Do I need to register this with the TTN  or set the frequency or something? Also, I can't help but think the pins on the module are slightly too short and may not be getting a good connection.</p>

Thank you for the help. That was all it was. I fired it back up again and issues commands from the correct command set and it seems to be working. Now to try it out more.</p>

<p dir="auto">the first thing you'll need to know is that the tutorial is using the <strong>868 MHz</strong> LoRa module whereas you are using the <strong>915 MHz</strong> LoRa Module. Unfortunately they don't use the same AT command set, so you'll need to adapt the tutorial for your module.</p>
<p dir="auto">For instance the 915 MHz module doesn't seem to have the <code>AT+LORAWAN=?</code> command and that is the reason you'll get the error.</p>
<p dir="auto">Please check out the related links section <a href="https://docs.m5stack.com/en/module/comx_lorawan915" target="_blank" rel="noopener noreferrer nofollow ugc">here</a>.</p>
<p dir="auto">BTW: the fact that you are seeing an error for the AT command given tells you that the RX/TX pins are correct.</p>
<p dir="auto">BTW: the <code>ASR6501:~#</code> line simply means, the modem went back to sleep.</p>
<p dir="auto">Thanks<br />
Felix</p>
