[Z-Stack GW] no RX data with UART

Other Parts Discussed in Thread: Z-STACK, CC2530, CC2531

With Z-Stack Linux Gateway (v1.0.1), when calling server invoke script, servers did not bring up properly.

It seems that there is a problem with UART RX, but not sure about the cause.

At UART RX thread, there was no data read, ('readcound" always was "-1").

From H/W view point, the UART port worked well when connected with serial console of a PC.

However, when connected with CC2530 Development Kit, it sends Tx data via UART port, but Rx data, readcount always was "-1".

Can you guess what is the cause of the problem?

Thanks and regards,

The default Zigbee Linux gateway uses CC2531 and USB CDC driver. If you use CC2530, I suppose you revise default HW and I suggest you check your CC2530 UART TX pin is connected to UART RC pin of Gateway correctly.

There was another process which use the same serial PORT.
So, RX did not run properly.

With CC2531 USB EMK (dongle), not with CC2530 DK, by using USB to Serial (CDC ACM), it is working properly.
