HI, 

I have a similar problem right now. I can easily connect with the device using TRCV_C, I can also send data with TSEND_C and it's all good. But the problem is, I'm not receiving two first Chars, they are replaced with '?' and '$R', while monitoring I can see that for a very short time the Chars are correct but in a blink of an eye they are replaced. When not using ad-hoc mode it's working correct but I am receiving data with dynamic data length so I have to use it. Any ideas why is that happening?

------------------------------------------------------------------------------------------
Split from TRCV not receiving the two first letters.

I don't know if that's the optimal solution, but maybe it will help someone with similar issue.

1. Send a positive edge to TSEND_C.REQ

2. Positive edge to TRCV_C.EN_R

3. Positive edge to TRCV_C.COM_RST

4. Go to step 1

This way, I got all i want in my target string.
