DIY Tracker on LLCC68 doesn't start

[Majakkf]

Hi, I recently built a diy tracker on esp32 and Ebyte E220 400M30S (LLCC68) The problem is that it doesn't start, I keep getting this error: Starting LoRa failed! State: -2 Everything is wired right What is the possible solution?

What are your Lora settings? Sf12?

SF9

power is on 18 (valid power units are 17, 20, 22... for your board max is 20). change it!

[Majakkf]

I changed it to 17 and it still doesn't start

[richonguzman]

the [RADIOLIB_ERR_CHIP_NOT_FOUND] (-2) you experience is because it can recognize the Lora Module

please check wiring / pins

[Majakkf]

Wiring is good and it still doesn't start

[richonguzman]

did you solve this?

[Majakkf]

No, maybe Lora module is dead?

[richonguzman]

could you test it with other firmwares?

What other firmwares are there?

is there a meshtastic one for this ESP32 + LLCC68 board?

Yes, meshtastic starts on LLCC68 (RA-02SC) but not on E220 400M30S which is also on LLCC68 chip

I received confirmation of another Ham OP which used ESP32 DIY with LLCC68 board with success

So I would suggest to double check the connections, the esp32 boards and finally see if E220 boards is working

did you try latest update of tracker?
