UART reference design for CC2650

Other Parts Discussed in Thread: CC2650

Hey,

I have a problems with the communication with UART between CC2650 and other MCU,

mainly that the read fails in the CC2650, especially a strange problem that some received bytes are receives as their most significant bit is logic-high while it is really logic low!

I am debugging this problem about one month! I dont know if it caused by FW or HW!

can you send me a reference design for UART connection to another MCU how to do? it makes me feel that there is a capacitor that it's value it too big so it holds the line high in special cases?!

Thanks.
