Hello, friends. I received my semtech lr1121 in quantity of 4pcs as well as esp32 pico v3 and esp32 s3. Can you tell me if I need to configure devkit before working, and also why I have not compiled target lr1121 esp32 tx?
Can you tell me which microcontroller i should use, i tried to run sx1276 on esp32 wroom32d but it didn't work. Please, if there are those in the chat who have run link on lr1121, post in private messages. Thanks

Looks like you don't have git installed

I am now faced with a wifi problem. Wifi won't turn on and won't connect to my point. also i'm not quite sure why the gemini tx has a half duplex to full duplex split? is it possible to expose a different gpio? i have esp32 pico v3, will it fit? Thanks

Thats because it's designed as an internal module. If you want for external then just define serial_rx and serial_tx to have the same gpio pin value.

am I correct in assuming that
"radio_miso": 33,
"radio_mosi": 32,
"radio_sck": 25,
I should connect 2 radio modules to these pins at the same time? Please share the schematic.

#

I can start the connection with only 2 pcs. esp32 pico v3 and 4pcs lr1121?

where do I connect dio1 and rst?
