I'm trying to find documentation on how to set up to receive a notification event when the puck is operating as a Central. Any hints, or is this possible (hope it is)?
It's not possible with the firmware right now - but we're working on it: github.com/espruino/Espruino/issues/959
Hi, I am using puck as central controller and I need to send AT serial commands to a 3G modem. Is this possible ?
@zarconi No. That profile is on Bluetooth Classic. I doubt the 3G modem supports Bluetooth low energy which is the only thing the puck 'speaks'. It may/may not expose a modem serial port profile on Bluetooth Classic (also called BR/EDR).
@zarconi if you're connected to the 3G modem via wired serial then it is possible - however I may have misunderstood your question. If you were asking whether you could use it with a Bluetooth-connected 3G modem then @billsalt is correct - that kind of UART over bluetooth connection is part of normal Bluetooth, not Bluetooth LE.
Thanks for this. I am using cellular or lora modem with wired serial lines to puck and connecting over internet.
Ok, then yes, everything is good. You should be able to use the 3G modem with Puck.js just fine.
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.
