Thansk for the update. Hope all is working now. IOT747

The thermistor will need to be connected to AIO0

Hi,
Please refer to the new maual and Datasheet on the IDC777. BATT_CONFIG will allow you the charging voltage levels and charging current level. BATTERY_STATUS will give you all the information about the battery.

Hi Marcin,

Yes, sorry, we had to discontinue IDC747 because the Qualcomm part in this module has been discontinued. This came to a surprise.

So unfortuantely, you have to move to the IDC777. The IDC777 has the same API as IDC747. It is very close to the BC127. You can see the commands at: https://www.iot747.com/download/idc747-uart-command-manual/

The IDC777 is the same as IDC747 in terms of features but it has LE AUdio (Auracast and Unicast) features. You can see how some of the commands work at the video section also: https://www.iot747.com/user-videos/

Hi Dirk,
Can you try AA3061D: https://1drv.ms/u/s!ArxXgcuMmkOHla0y2huU87im9pVCWg?e=mAOreC?
This shoudl have it fixed. It is also on the Cloud if you are doing upgrade over Bluetooth.

Hi, Yes, I have manaed to reproduce the issue using 2 DISKITs.

If the IDC777 is doing the OPEN UTXV, then the I2S IN works (You can hear whatever is on the I2S on the other side on the URX1). But the I2S OUT does not. The AUdio actually ends up in the Analog anway but nooisy I think this is a bug that was introduced in the latest firmware. So I’ll ask for it to be fixed.

Hello,
You don’t need a thermistor to charge the battery. Please upgrade to the latest firmware and using BATT_CONFIG and BATTERY_STATUS commands, you shoudl be able to check that it is charging as expected.

Hello,

I am not sure I understand your set-up. Could you please explain:

SetUp1: This is an IDC777 Module installed in a prototype (Host). The Host opens an UTXV with an IDC777 in a IDC777-DISKIT (Device). You do not get any I2S out from the IDC777 module in the Host?

SetUp2: The IDC777-DISKIT is the host (Host). The Host opens a UTVX with an IDC777 module in a prototype. You get I2S out from the IDC777 in the prototype?

Is that correct? Please send your UART logs on both side.

Please note that:

1) You must pair from the side that will be the host and do the OPEN UTXV
2) To get I2S signal, you need to SET AUDIO=1 1 and also, you need to have AUDIO_DIGITAL configured to be the Master (if you want the board to generate the clock)
3) Make sure you get the latest firmware version. Do you use AA-Flasher?

Thanks.

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.

Hello Luca,
Unfortunatelly, you need to send a few UART commands for the module to Inquire for close by devices and pair and open a connection.
So you would need a small microcontroller. IOT747 does provide firmware customisation but you need to contact info@iot747.com

Hello,
Sorry for the delay.
1. ADVERTISING ON and you shoudl be able to see the device using the IOT747 Scanner application (On Android or iOS). ex: https://apps.apple.com/gb/app/iot747-scanner/id1602815563 for iOS
2. WRITE command can be used at the end. When you use the WRITE command, it writes all the current configuration parameters to the Flash.
3. Yes, by default, the IDC747 powers on while Advertising. So no need to turn OFF>

Hi,
IN BLE mode, you have the indication (reliable but slower channel with confirmation of packets received) or notification (faster but with no acknowledgement). In Data mode and indication, the bit rate is over 100kbit/s. You can select indication or notification in BLE_CONFIG.
