The most common Bluetooth profile for implementing modern TV remote control functionality

Roman Alexeev

Other Parts Discussed in Thread: CC2541

I'm exploring a possibility to emulate Bluetooth TV remote control. And I faced a problem that I can't find any information about the type of Bluetooth, which TV manufacturers use in their devices. If they use Bluetooth Classic (BR/EDR), then I have to implement either AVRCP or HID profiles to fulfil TV remote control functionality. If they use Bluetooth LE, then I have to implement HOGP profile. So, could you suggest to me which Bluetooth profile is mostly implemented in modern TVs with Bluetooth support? If someone has experience with a particular TV model, which supports Bluetooth, then I will be also appreciated for any information about Bluetooth, which is installed there.

Roman,

I'm sorry for the delay in responding to your request.

Are you working with a TI SimpleLink product? If so, can you let me know the part number and the SDK you are using, or planning to use? I'll talk to the team to get you an answer.

Thank you,

Luis

Luis, thanks for your response. Right now we are thinking about whether we will need to use Bluetooth LE (HOGP profile) and/or Bluetooth classic (AVRCP and/or HID profiles) to emulate TV remote control for a major part of modern TVs. And depending on an accepted strategy we will choose an appropriate Bluetooth chip.

Roman,

I've asked the team and I'm hoping to have a suggestion in a couple of days.

Thanks,

Roman,

I found that most companies have moved away to BLE from BR. One big reason might be low power consumption.

In documents I found, I can see that we also chose the HIG over Gatt Profile.

We have a couple of resources that might be helpful for you: swru341b and swru343a (you can also search for those document numbers at ti.com).

I hope this helps.

Roman,

I wanted to share something more that I found: our Apps leader thinks that HID over Gatt Profile is the one most often used.

We have some examples for our CC2640R2 device.

See also this one resource (may not correspond to latest SDK).

Thank you very much, Luis!

You've made me confident that I have to choose using HOGP profile for a TV remote control emulation. I will explore documents, which you kindly suggested to me. And it would be interesting to try your CC2541 Bluetooth Smart Remote Control Kit for these purposes. You've helped me so much!
