I have since been diverted onto other troubleshooting but I no believe this was a serial port permissions issue.

When I used this command ls -l /dev/ttyUSB*

I could see that only the “root” user and the “dialout” group have proper permissions to use the serial port, so I added pi to the dialout group.

Thanks for your help

I am using two moteinos (RFM69CHW), one as a serial gateway and the other as a DHT node. The serial gateway successfully reads the DHT node's broadcast just fine on my laptop - I can see the temp and humidity scroll by in the serial monitor.

But when I move the serial gateway to my raspberry pi, on which run mosquitto and node red, the serial gateway seems to init and then dies. Here is the debug

Looks like my parameters for the serial node work ? - and I have a green light saying connected.

Watching the dht node in serial monitor, it looks like it no longer connects with the gateway:

But when I reconnect the gateway to my laptop, it works fine again.

Is this a power issue at the pi usb port? Workaround?

Any other thoughts /similar experiences????

How to troubleshoot?

Thanks in advance.
