Lost payload on ttn Stack V3

[bluejedi]

@xenotrax

I don’t know if I have a SX127x or a SX1262 LoRa module on my T-Beam module … don’t know how to find out. There is nothing written on the chip.

@bluejedi

The only way to see the difference is the text “SX1262” on the label on the LoRa module.

If there is no SX1262 mentioned on the label then apparently you do not have a SX1262 version.

@xenotrax

Is seems as there is no way “at the moment” to make a SX1262 work

There is but you would have to use a different library than LMIC (and there is little experience on the forum with SX1262 in combination with Arduino).

@xenotrax

does someone have a working example for the ESP32 and SX12xx ? to learn how to communicate with ttn.

What about searching the forum yourself first?

Have a look at: Big ESP32 + SX127x topic part 3

Start reading at the top. There you will find useful information, including a suggestion for which examples to start with.

If you have a T-Beam v1.x then don’t forget that you will have to configure the power management chip first (at the beginning of setup()), the code for that can be found in the T-Beam topic.
