Can I use it with TTN

[Schmittfinger]

Hi,
I'm interested in using this project/this softwarer with the TTN-Network (my board is using AXP2102-power managemt).
On designer2k2/Lora-TTNMapper-T-Beam#3 you wrote that it is also useable with TTN (you test it with both networks).

Which configuration is necessary to use it with TTN?
What are the necessary changes?

I'm quiet new in lora - so maybe I overlook something in your readme.

Thanks - Sebastian

Hello @Schmittfinger,
it works as is with TTN, a quick guide how i do it for EU:

On TTN create a new device with "Europe 863-870 MHz (SF9 for RX2 - recommended)", "LoRaWAN Specification 1.1.0" and ""RP001 Regional Parameters 1.1 revision A". Click "show advanced activation..." and select "OTAA".
JoinEUI with all 0 and then generate DevEUI, AppKey, NwkKey. Copy this 3 into credentials.h

hello I receive all the time message Initialise radio failed(-2). T-Beam is v1.1 display works and show Lorawan Mapper 0.0.6
I try all versions of lora chip 1262 / 1276 / 1278 none of them work

@neresus V1.1 is not tested by me, do you get power supplied to the lora module?

did you modify the credentials.h accordingly?

here you need to change the pins used: https://github.com/designer2k2/tbeam-lorawan-mapper/blob/RadioLib_SX1262/main/credentials.h#L62

For example CS is 7 not 18 and Reset 8 not 23. Thats how i read it from the schematic, please double check.

and here the actual radio: https://github.com/designer2k2/tbeam-lorawan-mapper/blob/RadioLib_SX1262/main/credentials.h#L68
