Allow to write to characteristics

[dzamlo]

Currently, it is only possible to read a characteristic. It would be nice to be able to write too.

It should be possible to enter data in multiple format:

• UTF-8 String
• Hexadecimal

I don't know what the interface would look like.

That is a good feature request, I am not really sure how to organise it. Do you expect to have vim like input for the data? Or loading from files? or maybe blendr should be staying the pure readonly browser?

Need to think about this more

[dzamlo]

I'm very new to BLE, so I'm not sure what is expected by most user.

I was thinking of having two keyboard shortcuts, one for strings, one for bytes as hexadecimal, and when pressed it display a simple text input to enter the value.

It is better to look on "nRF Connect" android app and make similar functionality.
