  Sorry no chance to get this working :/
  The other way works great. I'm able to advertise arbitrary data via BLE and get messages back :)

  Same problem after git pull. It keeps erroring while connecting (with and without named devices) :/

  There is a new error (after a fresh successfully npm i) noble: unknown peripheral null connected!

  Sorry for my late response. I tried your advice to remove the naming, but the output is identical.

  Note:
  I wonder how to "control" the puck in some way. I tried your advice at https://www.espruino.com/Puck.js+Node-RED.

  So I published {"payload": "LED1.set();\n"} (and also LED1.set();\n) to /ble/write/puck1/nus/nus_tx
  But all I get is:

  MQTT>/ble/write/puck1/nus/nus_tx => "{\"payload\": \"LED1.set();\\n\"}"

  Am I missing some advertising?

  I guess I got it now :)
  I finally receive something on /ble/advertise/puck1/1809
  Is it possible/"allowed" to reuse other BLE Service UUIDs for custom data (Light,Mag,Temp, BTN state) ?

  Thank you. !

  Hi,

  these days I received my puck and I wonder how you connect your pucks to some REST/mqtt services.
  For example: I have a openhab automated "smart home" and I want to push some data from the puck to the REST API of openhab (btn click, temp, light, mag etc).
  First I tried to use the fantastic EspruinoHub project, but BLE4 HTTP Proxy seems a bit limited with only 20bytes payload (and yes uri's are payload too :D). I hacked a bit the sources and get it working by "encoding" some requests, for example the request

  require("ble_http").httpRequest(device, "myItem/state", function(d) {})
  

  will be made to http://openhab:8080/rest/items/myItem/state. This can be a direction to go, but it needs some work.

  Another way would be the MQTT feature of EspruinoHub, but I didnt get it working (especially with custom data).

  What are you guys using for connecting your pucks to the world?

  Btw:
  Whats the proper way to ask for temperature via mqtt?
  Tried /ble/read/puck1/1809/2A1C so far

  Hi,

  I setup the Espruino Hub on my raspberry pi (2) and all seems to work very well. I can successfully run

  NRF.requestDevice({ filters: [{ services: ['1823'] }] }).then(function(device) { console.log(device) })
  

  and get the hubs bluetooth dongle as result. But if I run the full example from https://www.espruino.com/Puck.js+HTTP+Proxy I just get WARNING: Module "ble_http" not found.

  I updated my puck to 1.89, what Im missing? :)

  Thanks!

• Cannot read multiple Bytes from LSM9DS0 via I2C

  Hi,

  after my post I re-read the docs to verify that the LSM9DS0 is capable of block reading. Yes it is, but I overlooked something. The MSB of the register to read must be 1 for auto incrementing the address. I will give this a try later and add another post. :)

  Thank you.

  Edit: hehe you were faster :D
