  Hello,

  I used the default configuration settings for compile and send the code.

  I moved back to Espruino 2v10 and it has worked perfect!

  Thanks,

  Hello,

  I found an issue when uploading code to MDBT42Q. I used the espruino web ide, the device has the firmware version number 2.11.

  I've upload the code (attached here) to flash memory, to maintain it after power off. After sucessfully code upload the device sends me this message:

  Few minutes later the espruino seems to restart itself disconnecting the bluetooth conection from the laptop.

  The most curious part is that if I copy and paste the source code directly to the terminal on the same Espruino web ide, it works perfectly.

  I would like some help to understand the cause of this behaviour.

  Thank you,

  Hi,

  Yes, this what I think it's happening. Unfortunately I didn't have time to create a testbench to test it yet. I want to do it, as soon as possible, for sharing with you and try to discover where is the problem.

  Hi,

  As part of my research I seen this part of code, so I was confident that the indications will work. The problem appeared when I needed to communicate with the above mentioned device(Xiaomi Mi Scale 2).

  The characteristic that I need to use has only set as true the indicate parameter. I've written some code to subscribe using the startNotifications() function, the problem is that I only received one packet of data, after that it seems that the device get stuck as is waiting for the ACK packet necesary to finish the indication reading procedure.

  I will try to create using 2 espruino devices an example to do it more reproducible without buying a Scale.

  Thank you for your fast response.

  Hello,

  I'm not a experienced devOps but you can use cloudflare as DNS server, then you don't need to configure any certificate. You could use their proxy and configure a rule to connect to your server using http.

  Hello,

  I have a Xiaomi MI Scale 2 and I want to read the weight using an MDBT42Q using it's BLE. I've found the protocol defined here: https://github.com/oliexdev/openScale/wiki/Xiaomi-Bluetooth-Mi-Scale

  For reading the weight I need to subscribe to the 00002a9d-0000-1000-8000-00805f9b34fb Gatt Characteristic. This characteristic enables me to subcribe to it using indications (not notifications).

  I wolud like to know if it's posible to subscribe to indications in a similar way that is used for notifications (startNotifications function).

  Thank you in advance.
