7) Send commands to the device by writing to the Application Data From Host Length
characteristic, then to the Application Data From Host characteristic; receive notifications
that the device has changed the Application Data To Host Length characteristic, and read
the corresponding incoming data from the Application Data To Host characteristic.
8) The device will stay powered on until the host terminates the BLE connection, or until a user powers
off the device using the power switch. Powering off causes the device to terminate the BLE
connection. To conserve power, always power off the device when it is not in use.

To communicate with a device using the BLE connection, hosts should begin all commands and
responses with the following header:
Bit 7 6 5 4 3 2 1 0
Byte 0 0x00 = Get
0x01 = Set
Byte 1
… Byte n Request data as defined below and in section 3 Command Set.
The command / response for a Get report are formatted as follows:
Request from Host
Byte 0
0 (Get)
Byte 1 Report ID
Response from Device
Byte 0
Report ID
Byte 1 - n Report
Maximum report size is 63 bytes.
The command / response for a Set report are formatted as follows:
Request from Host
Byte 0
1 (Set)
Byte 1 Report ID
Byte 2 – n Report
Maximum report size is 63 bytes.
