Description

Dispatcher of the OnCharacteristicRead event.

DoOnCharacteristicRead is called when the data of a characteristic of a service from a remote device is read from the remote device.

This read operation may be triggered by any of the following:

• You actively requested to read the data of a characteristic using ReadCharacteristic.
• You enabled notifications for changes on a characteristic using SetCharacteristicNotification, the characteristic then changed on the remote device and the data of the characteristic was automatically updated on your end.

This event dispatcher receives the following parameters:

• ACharacteristic is the characteristic that has been read.
• AGattStatus is the exit status of the read operation.
