[App_rpt-users] Problem with Dual Node config with DIAL on RPi3

Steve,

 

Answers to your three questions:

 

If I power on the Pi with the second RIM unplugged from USB, the unit boots up and the heart beat on the first RIM is normal.  If I subsequently plug in the second RIM, its heartbeat flashes normally (after about 2 seconds) and the first RIM stays up, both heartbeats are flashing, not quite synchronously, but appear to wig-wag.  Life is good.

 

If I power up the node with both RIMs connected, the first RIM heartbeat comes on first, much slower than normal, and blinks irregularly for about 3-4 seconds.  Then the second RIM heartbeat starts to flash normally, and the first RIM stops flashing with the heartbeat LED on steady.

 

(this lsusb report is with both RIMs plugged in, and the Pi powered up – RIM #1 heartbeat on steady, RIM #2 heartbeat flashing normally)

In all three cases, no other usb devices were connected.  No keyboard, no mouse.  The 3rd and 4th USB connectors are empty.

 

 

channel driver is usbradio

in rpt.conf, rxchannel = radio/usb for first node, and rxchannel = radio/usb2 for the second node.

** This does not match the instructions in the allstarlink.org “setting up a two node system” how-to page. **

 

In usbradio.conf (at the end of [usb] stanzas) I added these lines since I am using the RIM interface pins to control a set of 4 relays.  Prior to adding these lines, USB communications would fail because output was not declared.

The second RIM on node 2 has no relay board, so these lines are not present in the [usb2] section of usbradio.conf

gpio5=out1              ; in, out0 or out1

gpio6=out1              ; in, out0 or out1

gpio7=out1              ; in, out0 or out1

gpio8=out1              ; in, out0 or out1
