I have a LogicMachine5 (Lite) and a CAN-R4-LoRa purchased years ago. Not using LoRa (it was a kind of end-of-year sales action at the time), but using the "R4" part.
Suddenly now it doesn't work anymore. Messages are still sent to the device (at least when looking at the CANX monitor tab in LM5), but device doesn't react anymore.
The hardware buttons to flip the relays on the CAN-R4-LoRa device are working: the lights go on and off.
24V supply is ok. But in LM5, CANX app, the device cannot be reached.
Programming button works (at least: the LED lights up when pushing it).
But even when prog button is on, can't see any device in the LM5 CANX app that has prog button on.
Have tried to disconnect and reconnect 24V power supply, have checked physical connection to CANX port, have done a long push on the prog button (after which some 'click' sounds could be heard in the device). Nothing helps.
It was working fine during years.
I did very recently do an update of the firmware in the LM5 (before that it was using the original firmware, years old), because I was experimenting with connecting energy meter Carlo Gavazzi to my LM5 (which works!). It is now this:
HW: LM5 Lite + Ext (i.MX6)
SW: 20240426
Could it be that I need to flash also the firmware of the CAN-R4-LoRa? (I don't have any other CANX device, can't compare to other CANX devices).
However I seem to have a EX1CANLRv10 (see attached photo), while only firmware for EX1CANLRv11 and EX1CANLRv21 is available on the website.
Is my device broken and do I need to purchase a new one? Or is it worth trying to flash new firmware, and what firmware should I use then?
Thanks!

try to do factory reset of R4 (press button for 5+ seconds), then load config again
if it does not help, try to install new firmware of R4, instructions are here https://kb.logicmachine.net/canx/flashing/
