Using the Zigbee shell through Segger RTT backend

[psychogenic]

Hello,

I tried enabling the Zigbee shell, through RTT, in my application and when that failed I built and burned the nrf/samples/zigbee instead, slightly modded to get rid of DK dependencies and enable RTT backend.  Still no go.

Logging is enabled and I'm connecting through the JLinkRTTViewer, and I can see that, so the connection seems ok.  But whatever I try to send just seems to sit in the down buffer and when I get to 16 bytes, it's full and nothing happens.

I've tried various line terminations (LF, CR, CR+LF) but nothing on the other side seems to drain the bytes.

I'm attaching a screenshot of the JLinkRTTViewer and the modified sample prj.conf.  Any input on getting input working would be appreciated.

Ok, a little more mucking about and I got it working.  For anyone having the same problem, the magic words were:

CONFIG_SHELL_BACKENDS=y
CONFIG_SHELL_BACKEND_RTT=y
CONFIG_LOG_BACKEND_RTT_BUFFER=1
