Thank you for replying to my previous comment,
I have bought the LoRa E32 433T30D from the following
Link , along with the TX433 JKD-20p antenna. When I checked using RF Setting software with USB to TTL, there is a message saying 'No Response from devices.' I have three LoRa devices, and all of them have the same message.
When I checked using the GetConfiguration library example with an ESP32 board and following the schematic you provided, I got the following results
RX MIC ---> -1
TX MIC ---> -1
AUX ---> 15
M0 ---> 21
M1 ---> 19

When I attempted to send a message with the following code, the LoRa did not receive any message response.
