Is it possible to use the Heltec WiFi LoRa 32 (V3) with a DTU?

#1

Hi everyone, recently I am working on some IoT projects prototype and I am a newcomer to it.

I have a DTU (EBYTE E95-DTU 400F20-232) and a Heltec WiFi LoRa 32 (V3). I tried to send data by LoRa from the DTU (by sending “123456” from a serial com port tester) and receive it by the Heltec, I did the same configurations on both devices (frequency, baud rate, serial parity bit, airspeed, transmitting power). I’m using the example code for the Heltec (LoRaReceiver) and seems it’s not working.

So I am wondering if it is not working at all with each other or if I have not done enough on the configurations?

Thanks for helping.

As best I can tell, the EBYTE E95-DTU 400F20-232 uses GFSK modulation, while you’re using LoRa on the WiFi LoRa 32 module. The SX1262 claims to support both but, either way, you’ll have to be using the same modulation method on each device.

Thanks for your reply, that gives me a path to do the research.
