hello, sorry but I’ve been busy these days, I tried doing as you said, the leds came on on all gpio except 21 (AUX) but using pinMode(21, OUTPUT); the led comes on.
however i noticed one thing all the leds light up low, but using pinMode(nGPIO, OUTPUT); the leds light up more, so i think there is some problem in the management of the gpio and you have to set the various pinMode()? in that case M0 and M1 would be in OUTPUT but AUX, RX and TX?

I realised that after entry 0x403c98d4 there were also these codes:

E (14) gpio: gpio_set_level(226): GPIO output gpio_num error
E (14) gpio: gpio_set_level(226): GPIO output gpio_num error

this?

i have only it in serial output

if you please, I tried to redo the setconfiguration, this is my code: https://codeshare.io/Odg6oW
but unfortunately I get this:

No response from device! (Check wiring)
12
Save mode returned not recognised!
11
No response from device! (Check wiring)
12

and if I use Serial2 the board’s usb port is not recognised.

hi, LoRa_E220 e220ttl(&Serial1, 21, 43, 44, UART_BPS_RATE_9600);
is it necessary to use pinMode(pin, INPUT_PULLUP);?

[Andrecolz]

hi, i did as you said, this is the output:

No response from device! (Check wiring)

hi, i just tried changing my constructor as you suggested: LoRa_E220 e220ttl(&Serial1, 21, 43, 44, UART_BPS_RATE_9600);
but e220ttl.available() always stays on 0, could it be a problem done during configuration?

[Andrecolz]

hello forgive me but I’m fairly new to this world of lora/esp32 so I’m not familiar with it, what is a controller?
do you mean the obj lora constructor?
if so this is mine: LoRa_E220 e220ttl(18, 17, &Serial2, 21, 43, 44, UART_BPS_RATE_9600);
but on second thought mine might be a different problem to Giuseppe’s, but I’m not sure, I should also try testing it on other boards like arduino, but my main interest was to develop for t-display-s3.
thanks for the help.

hello did you manage to solve the problem? i think i am in the same situation as you.
