Execute code/function on puck.js from another ESP board

Hi everyone
I am trying to set the time on Puck.js from another device (ESP32).
I am not able to run from the battery as my electricity meter sometimes gets stuck on pulse LED high and after some time hangs Puck.js and drains the battery. So I am running it off mains power (3.3v), but due to that and it sometimes rebooting, I cannot keep the time in sync with real.
My other ESP32 device is withing BT reach to Puck.js and I just wondered if I can make it connect to Puck.js and somehow set the time on it
Any help with time sync would be much appreciated =)

You could connect, but it's a lot of work. However you could make the ESP32 advertise the time via Bluetooth Low Energy (what are you programming the ESP32 with?).

You could then use NRF.requestDevice with a filter on the Puck to find the ESP32 and read the advertising packet direct from there.

which is exactly what is currently discussed in topic http://forum.espruino.com/conversations/372114/ It is just few lines on ESP32 to enable NTP over wifi and advertise time over BLE (if you are ok with accuracy to 1 second)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
