Unrecognized transceiver

[KingRat0011]

When I load the ping.ion to an Arduino pro mini on the UCA board, it works fine

15:44:37.655 -> Simple LoRa ping-pong with the gateway
15:44:37.655 -> Arduino Pro Mini detected
15:44:37.655 -> ATmega328P detected
15:44:38.832 -> SX1276 detected, starting
15:44:38.863 -> SX1276 LF/HF calibration

But when I load the https://github.com/CongducPham/LowCostLoRaGw/blob/master/Arduino/Arduino_LoRa_Simple_GPS/Arduino_LoRa_Simple_GPS.ino
to the same Arduino board, I get

15:47:37.655 -> Simple LoRa ping-pong with the gateway
15:47:37.655 -> Arduino Pro Mini detected
15:47:37.845 -> ATmega328P detected 
15:47:37.845 -> Unrecognized transceiver

Could you please help me with this? I disconnected the GPS module, but that did not help
