E220-400T22S Transmitter and Receiver Questions. Need Assistance Please. #76

Greetings,

Currently, I'm engaged with the LoRa E220-400T22S device, aiming to transmit signals from the transmitter unit and receive them via the receiver unit.

I have several inquiries and would be grateful for your assistance:

  1. Is it necessary to utilize a TTL UART Device for configuring key parameters in the module? If so, is this device compatible: TTL UART MODULE?
  2. Is it feasible to configure this LoRa module with Arduino? If yes, could you provide guidance on the process?
  3. Does the provided library support this LoRa E220-400T22S module?
  4. Given that I'm utilizing an 8KB microcontroller, the size of the library appears to be too large. How can I optimize the program's code? Are there any non-essential segments within the library that can be excluded while using it?

Thank you for your assistance.

  1. EBYTE has special hardware programming modules, see https://www.cdebyte.com/product_serch/E15-USB/1/ The company also has software for programming the module
  2. Yes, I do it all the time, see the examples
  3. No it does not,
  4. what are you trying to do? Do you want a library to a) program the module once, b) change settings at runtime, or c) send/receive data? if (a) try the programmer I listed above if (b) since you have only 8K MCU, you will probably need to write your own programming code, if (c) you don't need a library, creating a struct and using Serial.send(....) and Serial.readBytes(...) is all you need.
