ESP32-E22 No response from device

[luisgcu]

Hello, First of all thank you for your work in this library, looks good! I am having E22 Connected to ESP 32 I loaded couple examples, I have the following definition for ESP32 pins: // ---------- esp32 pins -------------- LoRa_E22 e22ttl100(&Serial2, 15, 21, 19); // RX AUX M0 M1 I Always gets "No response from device! (Check wiring)"
wiring is ok. Module actually transmits, I am able to see when transmitting using SDR sharp. I just get the error at initialization. I also tried the example Arduino_e22_getConfiguration, and I got this:

No response from device! (Check wiring) 12 No response from device! (Check wiring) 12

Model no.: 112 Version : 111 Features : 1101110

these are my connections with ESP32

• E22 ----- esp32
  • M0 ----- 21
  • M1 ----- 19
  • RX ----- TX2 (PullUP, 4.7k)
  • TX ----- RX2 (PullUP, 4.7k )
  • AUX ----- 15 (PullUP 4.7k)
  • VCC ----- 3.3v
  • GND ----- GND

Hi Luisgcu, if the connection was ok and the device works correctly I don't see any problem. Try to put 5v on VCC. Bye Renzo
