User defined data in standard GATT

[kjell bystedt]

We are going to build commercial applications that sends 20 bytes of sensors data. Could we use a standard Gatt ?

Yes, you should be able to use standard GATT.

Create a custom 128 bit UUID, that you use for your service and characteristc. Assign notification properties to the characteristic and max length at 20 variable length.

When the peer connect and configures to receive notification on that characteristic, you should be able to send 20 bytes of data.
