Lora conf - not receiving #18
Comments
I noticed that you only turned on the LD2 power, but did not set its operating voltage, you can try to add
but I think this is not the main reason. You can try it first. |
Hi @lewisxhe , i tried to change it and no change. Still nothing.
And here is the output i get
I even tried to change the antenna. |
I had a similar issue and it turned out that the jgromes/RadioLib library that the T-Beam was using has a default LORA spread factor of 9 and the sandeepmistry/arduino-LoRa library I was using on the LoRa32 SX1276 OLED and the default SF there was 7. Once I set them to the same value I was able to send and receive LORA packets between them. |
from where you can change these settings? |
With the RadioLib library the spread factor is set to the default value of 9 in the begin() method for the individual SX1276 module SX1276.h file. It can be changed by passing in a custom value for that parameter to begin() or by using the setSpreadingFactor() method. For the arduino-LoRa library, there is just the setSpreadingFactor() method as defined in LoRa.h |
Hi,
is it possible to send a lora payload from a T-Beam and receive it from a LoRa32 SX1276 OLED (v2) ? I if follow those two tutorials:
https://randomnerdtutorials.com/ttgo-lora32-sx1276-arduino-ide/ or https://randomnerdtutorials.com/esp32-lora-rfm95-transceiver-arduino-ide/, i can send and receive without problem from two LoRa32 devices.
But if i let the LoRa32 receiver ON and tries to send from a T-Beam T22V1.0, nothing seems to happen.
T-beam code: (some gps related vars are set but i removed gps code for clarity. GPS does work fine.)
What am i doing wrong ?
(if i am not in the good place for that kind of beginner issue, please tell me and i'll try to find a more suitable place for this..)
Thanks :)
