i miei componenti sono
LoRa 868 MHz 915 MHz LLCC68 Modulo wireless 22 dBm Lungo raggio 5 km CDEBYTE E220-900T22D SMA-K UART RSSI Trasmettitore Ricevitore DIP
e
RP2040
sto usando la libreia E220
ed ho modificato il codice LoRa_E220 e220ttl(&Serial2, 1, 10, 11); // RX AUX M0 M1 perche rp e diverso da quello originale

Hi, I have the same problem. Data size does not match! I think the wiring is correct
