LoRa - Firebeetle-ESP32 & LoRa TEL0125
Howard.Robson302 2026-07-16 22:41:26 54 Views1 Replies I have a set of 2xFireBeetle-ESP32 modules and 2xLoRa-TEL0125 and I have downloaded the library and the code from the GIthub here https://github.com/DFRobot/DFRobot_Lora/tree/master
I have connected Reset to D3 and CS to D4 onj both of the TEL0125 modules. The LoRa-TEL0125 modules are installed on top of the FireBeetle-ESP32 modules.
Is there anything additional I have to jumper?
I have loaded sendTest into the one FireBeetle-ESP32 and receiveTest into the other FireBeetle-ESP32.
I have the TX module outputting send packets, but I do not receive an valid packets. What am I doing wrong?
Hi, for FireBeetle ESP32, the default TEL0125 wiring should be CS -> D4 and RESET -> D2, not D3. The DFRobot wiki table lists D4/D2 as the default pins:
https://wiki.dfrobot.com/tel0125/docs/22278
So the first thing I would try is moving RESET from D3 to D2 on both boards, then use the default lora.init() in both sketches. If you want to keep RESET on D3, you need to pass the pins explicitly, for example lora.init(D4, D3), on both sender and receiver.
Also make sure both sketches use the same frequency. For TEL0125 that should be 868 MHz, so it is worth setting it explicitly on both sides with lora.setFrequency(868000000);
