HM-18 module for an Original 1.3b board?

There are great instructions for adding a BLE 4.0 connection to an Espruino original board using the HM-10 module. Has anyone attempted to add a BLE 4.2/5.0 module such as the HM-18?
It uses a CC2640 combatible chip.

Personally I haven't, but if it has the same pinout for GND/3.3v/RX/TX then I imagine the only difference would be in the commands you need to send to it...

HM-18 Module installs with the same pins as the HM-10 module. It’s advertised as BLE 5.0, and mine arrived with firmware v116, and there doesn’t seem to be an update for this module on the manufacturer’s website(http://jnhuamao.cn/download_rom_en.asp?id=1).
Like the HM-10, it is configured using AT commands, and has only two modes; iBeacon and a proprietary UART service. The AT commands can configure the module for lower-power and sleep modes. Gordon has posted iBeacon JS code at: http://forum.espruino.com/conversations/252971/

I initially wired up a button and pull-up resistor to the System Key, pin 23. According to the data sheet, pulling to ground either disconnects a connected module or resets to a default configuration if already disconnected. Power cycling the module also disconnects, so I removed the button.

I’ve configured a surface mount LE and 1206 resistor to shine through one of the board’s through-holes. Clear nail polish insulates the connections from the board, and the board still lays flat on a surface. The LED blinks when not connected, and stays on when connected.
A simple script to control the on-board red LED can be controlled via the nRF Connect app to verify operation.

function onInit() {
    USB.setConsole();
}

Serial1.on('data', function(data) {
    if (data=="o") LED1.write(true); 
    if (data=="f") LED1.write(false); 
    }
);

Pretty nifty that a $5 add-on adds BLE communication to the versatile classic Espruino board!

For some reason I'm not able to embed images or attach them. Here are the links to the images in case anyone would like to see what I came up with:

That looks awesome - thanks for posting up!

You say 'proprietary UART' - it's not the Nordic UART is it? If so you could then program Espruino with the Web IDE wirelessly - just like a Puck.js or other native Bluetooth LE device!
