questions of IDC777

[huma]

Hello,
There are some questions i want to ask. I am evaluating Bluetooth solutions for our product. There are several requirements.
1.Can CIS and BIS mode work at same time? if not, can the two work mode can be switch freely?
2.Can it receive A2DP(class) audio signal or le audio and relay it to another device(just like headphone) through leaudio(CIS or BIS)? I have read the IDC777 MODULE
PRODUCT BRIEF pdf file, I think the image on page 9 is the feature I want, but it seems to only support relay audio signal through BIS.
3.I have noticed that the 10 and 11 page of IDC777 MODULE PRODUCT BRIEF pdf file, the commit of link from module to module only wrote “Broadcast Music
Unlimited Devices” or “One to One Communication” or “Broadcast Communication”, I want to know if this is Le audio or Bluetooth Classic.
4.May I ask if there are significant resource limitations? For example, I have a device responsible for sending stereo audio(le audio), and the second device receives this audio and relay it(le audio) to the third device. Can we ensure that the entire system can transmit stereo audio signals with a sampling rate of at least 48K.

Hello Huma,

Sorry for the delay. For now, what we have is:

1) BIS (Auracast): Receive or Transit stereo and 48 KHz. If one IDC777 module is Tx, then you can connect an infinite amount of IDC777s to receive the stream. Please check out this video: https://www.iot747.com/aiovg_videos/idc777-in-broadcast-transmit-and-in-broadcast-receive-mode/

2) A2DP Classic then BIS Relay: The module can receive an CLassic Bluetooth A2DO Stream and then Broadcast over BIS (Auracast) with LC3 at 48 Khz and Stereo. Please check out this video: https://www.iot747.com/aiovg_videos/idc777-receiving-a2dp-classic-and-streaming-over-le-broadcast/

3) CIS: We can receive a CIS Audio (Unicast) – Both for Calls (Bi-Directional) or Music. We will post a video shortly on the website.

4) Classic and LE Connection: We can have at the same time 2 devices connected (One Classic and one LE). We have a vidoe with One BIS and Once Classic: https://www.iot747.com/aiovg_videos/idcc777-switching-le-and-classic/. We haven’t tested this scenario too much but the IDC777 is capable.

What you want (IDC777 –>IDC777 –> IDC777) using BIS. So IDC777 receiving a BIS and transmitting a BIS at the same time is not implemented. But we are developping new features on the IDC777 and we have this use case scenario on our list. So you would need to check or subscribe to our newsletter.

Thanks.
