6.5.5 of SH-2 Ref manual: "Note that SH-2 protocol version 1.0.1 and higher will send Get Feature Response messages
unsolicited if a sensor’s rate changes (e.g. due to change in the rate of a related sensor."
For ex. after calling disable_rotation_vector(), the following response packet will be sent:
I (3497) BNO08x: SHTP Header:
Raw 32 bit word: 0x15000205
Packet Length: 21
Channel Number: 2
Sequence Number: 5
Channel Type: Control
Body:
0xFC 0x05 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00
The 0xFC indicates it is a get feature response, the 0x05 indicates it is for the rotation vector, the rest of the body will be 0.
Lets flush this response as it's currently detected as an invalid packet, we don't care about it.
It might be wise to detect the response for the respective report being disabled, but is probably not necessary.
