Hey i have Lora Ebyte E220 866Mhz 30dB
microcontroller Rasspbery Pico
transmitter connect to GP0 and GP1 TX/RX
AUX not connect, M1 to 0V and M0 to 3,3V
receiver connect to GP0 and P1 TX/RX
Aux not connect, M1 to 3,3V and M0 to 0V.Wants to send three messages coordx, coordy, coordz in sequence read them in the same order, and write them as “long” variables. I have set both Ebyte devices to channel 83, the transmitter has address 16 and the receiver 17. The key for both is 26542.
The variables I send are also in a “long” format
How do I do this?
Sorry but my comments are in Polish in my code: -

Hey, I used TTL to USB programmer and configured LORA and connect to Raspberry Pico Aux pin its works very well, but I don’t have knows what you mean by setting the correct delay. GPS receiver data are receiving frequented 1Hz and I set WOR in Lora to 1000ms. My GPS has pin PPS waveshare L76X is it possible to synchronize the transmitting lora with the received GPS signal?

Hi Piotr,
To understand look at this line’s code. If the AUX pin is settled, I check when It’s going LOW else I add a big delay to wait for the device to complete the operation.

Hey
The GPS has a PPS pin that triggers a high state every second, and I would like the LORA to send at the same rate as the GPS receives data, which is 1Hz it’s possible?I used to check the auxPin and PPS pin from the GPS module, whether they are on high value in my code attached example.
“while (digitalRead(ppsPin)==HIGH && digitalRead(auxPin) ==HIGH)”
