API usage on ZB coordinator node

Hello, this is my first post here and it seems the first post in the forum.
Hmmm… I hope to be in the right place :slight_smile:

Now the question: I’m testing a XBee series 2 (XB 24-B) with coordinator firmware 1120.
The I wrote some code on the PC to control the device using API frames.
When I send AT commands, the module seems to give the expected answer but:

  • instead of returning a frame type 0x88, it returns 0x3f
  • consequently (?) the checksum is wrong.

I don’t know if this has to do with the escaping sequences. On the other hand escaping seems to be not mandatory and I prefer not to use it.
Do you have any experience you can share?

Tks

Problem solved… fortunately it was not hardware-related!
