I have two T-Beams, the one T-beam I want to be a BLE gateway and then re-transmit on Lora to the distant T-Beam, then a serial output from this T-beam will be used into a Raspberry PI. The transmission will be only a packet every 10-15 min, very low bandwidth and short time on the air.
I have just started to search, but not found a example. I will continue searching in the background for one, but will be a great help is someone have a example.
if the LoRa communication is working it appears you have two tasks left
BLE to T-beam - have a look at File>Examples>ESP32 BLE Arduino for sample programs- have you implemented the code to send BLE to the T-Beam or have some ideas
T-beam EP32 to RPi - are you planning to use WiFi for this? e.g. TCP or UDP client/server?
