Let's Control It

I'm trying to get a Wemos D1 Mini (flashed with the latest ESP Easy release) to talk to a JY-MCU bluetooth module.

I assume I should use the "Communication Serial Server", but what value do I put in for the "PORT" ?

I can pair to the module from my mobile phone and send data, but nothing appears at the Wemos end.

If any one has got the serial communication to work, could they share the basics with me.

Kind regards from David.

I've got my mobile phone (acting as a terminal) talking via bluetooth to the HC-05 bluetooth module that links to my Wemos D1 Mini.

I can send data to the Wemos and using a rule get it published via MQTT to Node-RED.

Also if I reboot the Wemos I can see all the boot-up messages on my phone.

So all of this seems to indicate I have some sort of basic communication between my phone and the WeMos.

Two questions...
(1) How can I extract or find the data that was sent to the Wemos ??
(2) How can I "publish" serial data from the Wemos to my phone ??

Any help or guidance would be appreciated.

Hi to one and all,
I'm still trying to get the serial port working on a Wemos D1 Mini.

This is what my basic rule looks like...

on !Serial#* do
publish david,%eventvalue%
serial "fred was here"
endon

I get this MQTT message returned to Node-RED when I send red from my terminal (phone)... " david : msg.payload : string[11] "!Serial#red"


Two questions...
(1) How can I extract or find the data that was sent to the Wemos ??
i.e. %eventvalue% gives !Serial#red" - I was hpoing it would give "red"

(2) How can I "publish" serial data from the Wemos to my phone ??
i.e. What's the correct command as "serial" doesn't seem to work?

Any help or guidance would be appreciated.
