UPDATE: openenergymonitor provided fast support and shipped a working replacement part.
Hi, I’ve just received a new rfm69pi v3.1 (and a couple of emonTX V3’s ) and have spent the best part of a day trying to get something working, to no avail.
The first few times I powered up the raspberri pi (2B running raspbian wheezy) , the LED on the board turned solid red after a while. After solving permission issues and disabling kernel console and inittab console on ttyAMA0, i’m still getting “Device communication error - check settings” from emonhub.log
-I’ve tried 9600, 38400 and 57600 baud (powercycling between every attempt)
-I’ve tried stopping emonhub and using minicom with all baud rates - result: no data whatsoever after “Press CTRL-A Z for help on special keys”, and no response to any commands
-I’ve tried 2 different Raspberry Pi 2 boards
-I’ve tried using emonSD-17Jun2015.img (same result: no response in minicom, emonhub has error as above)
-I’ve tried a really beefy USB power supply, and removing the wifi dongle, in case of power issues
-I’ve insulated the antenna solder point from the GPIO headers on the pi so it doesnt short.
-I’ve tried reflashing the firmware via the PI (results in a whole heap of avrdude-original: stk500_recv(): programmer is not responding. avrdude-original: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00)
So, after a frustrating day of no results, is it safe to assume this module is dead?
If anyone has any ideas, i’d be super keen to hear them!
