voice data and activate the pressed key event.
3.8 - Couch mode
a) If a key or multiple keys are pressed continuously for more than 30s, the remote stops
transmission (except pairing combination) in order to protect the battery discharge.
3.9 - OAD mode
a) OAD can be made in overwriting method.
b) Image A device name: OAD BOOT
c) Image A version: 0xFFFF (Fixed)
d) After connection, the STB checks the version number of the software in the remote to
confirm if this is the most updated one.
e) If any software update is needed, STB sends the command to the remote to move to
Image A. Commands are defined in the Appendix 1 - Attribute Table for OAD.
f) After receiving the command from STB, RCU needs to re-boot in Image A.
g) After finishing boot-up process and connecting to STB, the software update starts via
OAD.
h) If the software update is made successfully, the remote reboots in the image B.
i) If the software update has failed, the remote reboots in Image A and retry it from step g).
3.10 - Key codes
a) In Bluetooth mode, HID Profile is used.
b) In IR Mode, NEC format is used
