Hello!

I will implement the data exchange between the module and the device Sim5360e through UART2. I write in the Lua, AT commands to send / receive information via the UART2 did not find - so use internal devio function.

Code:
  local msg,count=getHex(str)
  local unswer
  devio.open(3)
  devio.write(3,msg,count)
  unswer=devio.read(3,4000)
  print(unswer)
  devio.close(3)
When connected to a terminal on the PC - see the correct incoming message, the module enters the mode of reading, I send data through the terminal, but after a timeout (4000 ms) unswer = nil. Data from the terminal out exactly correct - checked by another device.

Can you please tell, how do I get an answer to my message?
