At the moment I flashed the Remote and everything seems to be working as it did before, but Bus 2.1 (O3) and 2.2 (VOC) aren’t being reported. Since there was nothing plugged into Bus 1.1, I plugged O3 in there and now it is being reported. Also, O3, plugged into 1.1 seems to be getting power during what I think is the sensor heating cycle. Same happens with VOC plugged into 1.1. When I unplug and plug in VOC or O3 into 2.1 or 2.2 I get the red PWR led flashing then a quick green INFO led, but then nothing after that.
Using the polling example tells me more of the same. Anything plugged into 2.1 or 2.2 doesn’t communicate, but both sensors are ok when plugged into 1.1.
If I comment out these lines in EggBus.cpp, it reports no more devices on bus #2.
Looking a bit deeper, line 55: rc = twi_writeTo(addr, &data, 0, 1, 0); returns 0 for anything on bus 2 and does not pass into the conditional.
Any ideas?
