Hi all,

I'm using an external bluetooth module that notifies me to the smartphone the changes in the values of two sensors that have UUIDs of different service and characteristics. I use "call BluetoothLE1.RegisterForBytes" together with "when BluetoothLE1 .BytesReceived" to receive data. But I can see the value of only one of the data while I would like to be able to separate and visualize them together.

Can someone help me?

Thanks

Evan Patton

You should be able to call RegisterForBytes for multiple services/characteristics and get updates for both. In the BytesReceived handler, you can then branch based on the characteristic UUID to visualize the two streams separately.

Regards,

Evan
