I'm trying the uartecho_CC2640R2_LAUNCHXL_tirtos_css. But I changed uartecho.c to get readcallback.
If I send 1 by 1 byte, sometimes I lost connection. I dont know if I have something wrong in my callback or if I have to declare the writecallback in order to synchronize.
The same thing occurs when I declare a greater size in my buffer.
19:20:04: a
a <--response
19:20:04: a <--no more responses
19:20:06: dsa<--no more responses
19:20:07:
19:20:09:
The same response is when i send 8 bytes, I lost connection
19:22:26: 12345678
12345678<--response
19:22:28: 12345678
1<--response
