I use a CR95HF with UART communication. I make the startup sequence with t0= 200 us. I have 30 boards with CR95HF. One of them don't communicate with my microcontrolleur. I change t0 = 250 ms and after this operation, the communication begin. Why ?

Can I find a startup sequence with the typical values and maximal values ?

I have a second problem.

I want use the calibration process to increase the lenght of reception but this command don't send response.

With the other commands, I receive a response.
Why ?

How much the calibration increase the lenght ? (millimeters or centimeters)
