Is my approach completely wrong here? Should I be using Test mode for the Loras? This will operate in a farm field in upstate NY (where we launch our rockets) and there is no internet access. Is there any way to have these LoRas operate on specific addresses? I found the AT-MSG = “Data to send” command but idk how to configure the receiver and transmitter to talk to one another.
Also, I’ve tried to configure the receiver to have a higher sensitivity by changing the spread factor from SF7 to SF12. I do this by changing:
mySerial.write(“AT+TEST=RFCFG,868,SF7,125,8,8,14,ON,OFF,OFF”);
To this:
mySerial.write(“AT+TEST=RFCFG,868,SF12,125,8,8,14,ON,OFF,OFF”);
When I do this the lora never receives any packets. I have a similar issue with the output power of the transmitter as well. When I try to increase the output dBm to a higher number (it’s defaulted at 14) to a higher value, they behave unpredictably. Can you guys also assist me in the correct AT command to increase the spread factor of the receiver and the output power of the transmitter? As you might’ve notice by now I have a very simplistic understanding of how to use these devices. Please address these concerns above and lmk if anything is unclear. Please, please respond, the success of my rocket team is on this deployment code and I cannot find any understandable information besides the AT command manual.
