ZigBee module ?

this could be a game changer.
how many ZigBee compatible MCUs are out there?

please do not consider a discourse(.org) type forum - this awful style gets overused lately

I have also just found the RTL8720DN.
looks like its fairly new.

this should work with
var wifi = require("ESP8266WiFi_0v25").connect(Serial2, function(err) {
i guess?

I don't really need it for speed, but for the limited channels on the 2.4 GHz network.
I am currently looking for an alternative to wifi for my IoT devices,
maybe something like Zigbee or I just read about EspruinoHub.
Sooner or later I want to separate my normal stuff from the IoT stuff.

it there a compatible 5 ghz wifi modul?
i see only the esp8266 but its only 2,4ghz

it does, tnx

as i havent got a MDBT42Q jet,
it would have been interesting how much much of the 512 kb flash is
left for logging - but i guesstimate its more than enough

tnx,
i think i'll get a puck to test and try to find 1 or 2 bare MDBT42Q modules
if it works like i expect.

sounds good.

is there a way to find out/estimate how much space is left from the 512k flash to store
time/value pairs?

Hi,

I want a small data logger with only
the pure MDBT42Q, a CR2032 (or similar) and the built-in temperature sensor.
Is this sensor good enough for recording the room temperature every 15 min
(for about 7-14 days) without requiring particularly high precision, but it should not drift too much when the voltage drops.
Does the chip heat up too much to record the room temperature?
(Maybe even secured under glue)?

Or do I need something like a DS1820
Has the board enough power to drive this sensor?

glad to hear it stays.
on coolcomponents.de its disontinued,
on berrybase its out of stock.
they have a puck.js v2 - is there significant a difference to 2.1?

hi,

in most shops the MDBT42Q is out of stock or even listed as retired.
Is there a new version of a mini breakoutboard ahead?

i totally get that this is not a high priority

it really is nice that it allready kindof works like want,
but its a different story to just plug in a usb stick and find some text with explanations,
without any further knowlege of that product.

i just wanted to know if its possible at all or if its somehow against
the basic philosophy or capabilities of the espruino project.

circuitpython has a repl too, i dont know how different it is to espruino

i have two usecases where i would like to have a usb device.

1. when i have a project eg a garage door opener with a code pad
   and its all done, i would like to have the code and some doku with
   the values to change and maybe parts to use, so if i come back 20 yeas later i
   immedeatl know what to do without reverse engeneer what i did ages ago.

2. When i e.g. built da datalogger and install it at a remote location,
   i can just call someone and copy the cvs file, and maybe the new code,
   without that they have to know anything

i think this would be possible with circuitpython - but i cant stand pythons syntax.

hi,

is it possible to use Espruino like circuitpython?
With a USB Drive option when connected to a pc to upload
the code, docs and logs in plain text?

Hi,

is there a new Board in the works?
like something based on ESP32-S2 or Teensy 4.0/4.1?

i do like Javascript on MCU but the pico seems to be a bit outdated and underpowered
considering its costs.

A more recent and powerful board with offical firmware would be really nice.
