Hi Draven,

I tried with the latest firmware. It had the 2 x IDC777-DISKIT with default configuration except:

1) Borad1: transmitter. On the AGHFP. I changed PROFILES=ON 0 1 0 1 1 1 1 

2) Board2: receiver. On the HFP (headset), I changed AUTOCONN=1 3

I kept plugging/unplugging power and then doing Call 12 incoming on Board1 and Call 13 answer on Board2 and I could hear all the time Audio when the SCO was opened.

Could you please try again on  your side with IDC777 DISKIT, latest firmware and Default configurations?

Hi Draven,

I have tried many times with the new firmware and I can’t replicate. Anyway, if you found a workaround then it is all OK. If  you have trouble in the future, please try on a DISKIT with the latest firmware, minimum CONFIG changes and clear steps to replicate and I will try again. Usually a video also helps in case we spot anything.

Hi, They run at 3V3. You can configure them to boot for party mode without any host. The latest videos at http://www.iot747.com show this. IOT747 Support

Hello Anthony,

Yes, the IDC777 can be updated via Serial Interface. You can test it with a DISKIT using AA-Srial-DFU (https://www.iot747.com/download/idc747-aa-flasher-2/) and one of the ‘.bin’ files from the firmware section (Please use .bin, not the .xuv files which are for the AA-Flasher).

We can also send  you the source code (pythong script) under NDA if you would like to integrate it in your firmware/application.

Hi Loris,

1) We have implemented the feature to encrypt Auracast with BROADCAST ON 2. But I will ask.

2) We have on our list of required features a feature to prioritise Auracast announcements. But I don’t have a date for it yet.

I will put the request for these features. Could you let me know when is your production date and the approximate volumes you are likely to ship? So we assign a priority. Thank you.

Hello Loris,

If interested in the announcements, please find a draft release: AA3267D.xuv

There is a new Command called ANNOUNCE (For the transmitter) and a new CONFIG called BCAST_PRIORITY (for the Receiver).

Attached draft Manuel with new command and config. IOT747 Support

Hello,

Could-you please explain the scenario with a Diagram and also a UART log?

Hi Loris,

Are you streaming 4 Mono Audio Streams? And each subgroup is listening to one of the Audio Streams? Something like: https://www.iot747.com/aiovg_videos/idc777-auracast-4-different-streams-at-the-same-time/?

We have not tested this configuration. But normally, it should work. So if  you do Announce, the BIG (all subgroups) has priority and it might work. What do you observe? Please send your UART LOGs.

Hi Loris,

I think the Announcement is a flag for all the subgroups but I will check when the engineer is back from the holidays.

That send, you know that you can use the SEND ‘subgroup1-P’ for example (or any character) and this is received by all the receivers as (Subgroup1-P). Then your host can pause the A2DP and play the Auracast. So you could completely control the links with any of of the receivers. But that would require more work on your processor.

Hello,

I’m sorry for the delay. I think the mistake is PROFILES=ON 0 1 1 1 1 1 1. This is probably causing the Panic, because you can either be a transmitter or a receiver but not both.

Try with SET PROFILES-ON 0 1 0 1 1 1 1 for Tx or SET PROFILES=ON 1 0 1 0 1 1 1 for Rx.

Hi Guido,

There is a typo in the document t. It should be like the below:

: (Phonebook entry)

• 1-(Default) Main phonebook folder
• 2-Incoming call history
• 3-Outgoing call history
• 4-Missed calls history
• 5-Combined call history

Any other value will return the Main phonebook folder.

Also, we do receive inputs on the iPhone for all values. We use the commadn pb_pull 1c 1 2 20 0 85 (We saw that you forgot one parameter in  your text PB_PULL 1C 1 30 0 85 but it was maybe a typo). Please note that yo uhave to allow to Synch Contacts on the iPhone, Otherwise, it returns nothing. See picture below. Also, we gave some UART examples below.
