I am not sure. My knowledge is mostly about the hardware and software provided by Nordic Semiconductor. As this framework is developed by Evothings, i think you will find better answers by contacting them or posting on their forum.

I did it yesterday, but it doesn't work too. So is it a question of buffer ? ( new Uint8Array(buffer [, byteOffset [, length]]); on your website)

I am no expert with javaScript, but i think new Uint8Array([13, 14,15]); will create an array of three bytes with the values 13, 14 and 15. (source) I could not find documentation for the function app.device.writeDataArray, but i guess it sends all the bytes in the array.

Hello, Here is a tuto that i used to custom my application : evothings.com/.../ For example, if I want to send "13" on my characteristic, I use the line : app.device && app.device.writeDataArray(new Uint8Array([13])); But it doesn't work with a value more than 255. Unfortunately, Evothings generate automatically the app, it can't give the app source code.

Hi. Can you point me to any resources regarding how you made your application? Evothings it not something i have used before. It is usually a trivial task to send how many bytes you want in a packet (up to 20), but it really depends on the framework you are using. Does Evothings generate the app directly, or give you source code which you then compile into an app?
