LoRa-E5 Dev Board No Response in Serial Monitor when typing AT


I’m using the LoRa-E5 Dev Board. After installing USB to UART driver, I connected it via USB-C. I got a connection but when I typed the ‘AT’ command I get no response. The baud-rate is correct as well as ‘Both NL & CR’ step. I accidentally clicked upload but canceled it within a second, I’m afraid that’s why I do not get a response. Since I do not have the code, I cannot proceed. Is there a way to fix this?

Best regards,
