LE Read Remote Features.

The description below is extracted from Core_v5.4, Vol 4, Part E, Section 7.8.21

This command requests, from the remote device identified by the Connection_Handle, the features used on the connection and the features supported by the remote device. For details see [Vol 6] Part B, Section 4.6.

This command may be issued on both the Central and Peripheral.

Note: If a connection already exists between the two devices and the features have already been fetched on that connection, the Controller may use a cached copy of the features.

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Read_Remote_Features command, the Controller shall send the HCI_Command_Status event to the Host. When the Controller has completed the procedure to determine the remote features or has determined that it will be using a cached copy, the Controller shall send an HCI_LE_Read_Remote_Features_Complete event to the Host.

The HCI_LE_Read_Remote_Features_Complete event contains the status of this command and the parameter describing the features used on the connection and the features supported by the remote device.
