Using multiple ESP32 "Things" - it looks like last one added to gateway is the only one working correctly

[ianarchbell]

I have a a set of ESP32-based examples running on our oddWires boards here:

https://github.com/iot-bus/iot-bus-mozilla-iot-examples

They all work fine individually and the library was easy to use. However, running more than one at the same time is turning out to be problematical. I do not know whether I am using the library incorrectly or whether there is an issue either in the library or gateway. For example. If I add a relay board I can happily turn it on or off using the moz-iot interface and I can turn it on/off locally using a touchscreen interface and the associated property is updated correctly in the interface. Once I add a PIR sensor or anything else I cannot control it from the moz-iot interface.

Running gateway in debug mode the gateway output is:

Unexpected end of JSON input often means there is none. However, I don't know whether there is malformed JSON on the adapter. It would be useful if what was there was logged.

I'd appreciate a pointer on where to go. If you need anything else please let me know. Thanks, Ian.

Each has a unique MAC address and IP address:

This is over a year old. Please re-open if there is still an issue, since there have been quite a few changes since then.
