Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

RPi serves as a server, PC is a client. PC sends a request, RPi sends a response. In the simplest case, RPi constantly sends data packets in UDP format to the PC with some interval.

Hi Peter,

I am not sure whether it is intended that
OPTION SOCKET portno can be included in code to allow switching of ports within the program but I have discovered that if it is included in the code, then it silently wipes out the program as soon as its encountered.
In the following code the first OPTION LIST is executed and prints out,
OPTION SOCKET 8085 seems to do its thing as a later manual OPTION LIST will show it sets the option, but the second OPTION LIST in the code is never executed and the program itself is deleted. i.e. LIST will show no code being loaded.

Hi Peter,
Is there an example of using TRANSMIT HTML to initiate a request from the pi.
.e.g a request such as below, or is TRANSMIT HTML only for responding to a request.

There are two types of OPTION commands as per Micromite. There are those that can be included in a program e.g. OPTION EXPLICIT, and those that permanently configure the environment e.g. OPTION LCDPANEL. The latter cause a reboot of the code and in the case of the Pi-cromite this of course wipes out the existing program.

At the moment OPTION SOCKET is a permanent setting but it could be either I don't have a strong view

No, the current support is as a TCPIP server. You are talking about the Pi-cromite acting as a TCPIP client - I'll have a look at it for a future release together with client and server UDP support
