[RC232] Maybe you have some documents or test reports about the influence of the data rate to the range in the same system?

There are some general rule of thumbs that can be used.

Doubling the data rate give 3dB less sensitivity.
4x data rate give 6 dB less sensitivity.

6 dB less sensitivity is used as approximate 50 % range.

2.4 kb/s = x meters
9.6 kb/s = x/2 meters
38,4 kb/s = x/4 meters
Etc.

  • [RC232] 2. If the module is powered down when not required for RX/TX, what is the power up time before it can be used to transmit? – is there failsafe way which indicates WHEN the module is ready to transmit, or determine this by checking something?
  • [RC232] What should I check to confirmt that my module is correct connected
  • [RC232] “We enable the RTS/CTS option in the DK and we send message longer than 128 bytes (the max buffer size) so we need the CTS to separated the massage. We test this with scope: 1. In the CTS we didn’t see change (I suppose all 128 bytes it needs to change) 2. Also in the Tx/Rx I suppose to see a break in the 128 bytes, but it takes all the massage 3. When I try connect this module to PC, only message shorter than 1024 bytes success to send “
