Is there anyone using MQTT as gateway for connecting to openHab running on another Rpi. If so please help with any links, post or any information to direct me on the right path.
thx for reply
yes dragino HE works like yun I think.
for linkit as the product seems new, there is a little bit less docs. but I will see, price was so interesting that it was too much tempting lol.
I will tell you what I can get...
for fun, I have not presented yet, but I have a board in progress for raildin : 8x relays + 8inputs for yun and I added ethernet connector+hub usb chip
As promised, what I found so far: the following dockerfile yeilds a usable cross-compile environment, provided you use it with a Makefile.
FROM ubuntu:xenial
RUN apt-get update \
&& apt-get install --yes \
vim \
build-essential \
git
RUN git clone https://github.com/raspberrypi/tools
RUN git clone https://gist.github.com/3873805.git /build
WORKDIR "/build"
CMD ["/usr/bin/make", "CC=/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-gcc"
, "HelloWorld"]
# Seems I need a real makefile for the above to work.
For cross compiling mysensors to work, hoever, you also need to properly seed the variable in configure, for it to work correctly. This is where I left off.

@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze.
Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices.
And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant.
