Please use the latest firmware which is under Suport/Firmware. It is currently AA3340D, it has the new HFP_CONFIG setting which includes LC3_SWB. If you disable it (it is disabeld by default), the firmware will act exactly the same as before. if you enable it, the IDC777 will open an LC3_SWB SCO if the other device supports it. Thsi works for HFP and AGHFP so if you take 2 IDC777, you can test it. See video at: https://www.iot747.com/aiovg_videos/lc3-super-wide-band-demo/. IOT747

Hi, There is a tool to put the IDC777 into RF test mode. But you need to sign an NDA for us to release the tool. Could you please file a ticket support at: https://www.iot747.com/support/open.php with details about your project and we will send you an NDA to sign. Thanks. IOT747 Support

Hello,

If SIDETONE=OFF xx, then it is disables and xxx value is not used. You shoudl not hear your own voice in the Speaker.

If SIDETONE=ONN xx, you will hear your own voice with different volumes. 0=-49dB and 13=-49+3*13=-10dB.

Hello,

You are Broadcasting with the same Broadcast ID 223344 2 different streams. This confuses the App as it is the same Broadcast ID. You need to use 2 different Broadcast IDs as these are 2 different streams. Use BCAST_CONFIG to change the Broadcast ID.

Please test the latest firmware as some fixes were done after the latest UPF.

Hi Mike,

It seems that you have faulty hardware. You would need to check all your hardware and compare to the DISKIT. The DISKIT and DISKIT schematics have to be used as a reference. the IDC777 cannot go into bricked mode. If the voltage applied is not stable and dips below 3V, it can end in a weird state. but power OFF and POwer ON again should get it back up and running.

You can RESTORE if you hold PIO3 at boot. See below from the manual. But it seems more likely this is from your hardware.

Hi Mike,

What firmware are you using?

Hi Mike,

CALL INCOMING and CALL_RINGING are 2 separate notifications from Bluetooth. We show them both if you need them. For HED, always compare with the IDC777-DISKIT if you think there is an issue. the IDC777-DISKIT always serves as a reference. 

Also, on the newer firmware versions, we display also the number and caller name if he get it. We also have PBAP and MAP. But if you have AA3170D, then it’s fine, you won;t have all these notifications.

Hi Mike,

IDC777 can be HFP or AGHFP but not both at the same time. This is on the Roadmap but we don’t have a date for the release.

Hello Mike,

1) For some configuration, you need to do a RESET for it to take place (For example AUDIO). For otehr, you don;t need to RESET. The manual tries to let you know whicch ones need RESET. But usually, it is better to RESET for safety.

2) Once you do a WRITE, it writes the new configuration on the Flash. So you can Reset in software or Hardware and it’ll work.

Hi Bruce,

The Windows DFU tool does not allow parallel processing.

However, if you sign an NDA (Our NDA is under Support/Documents at https://www.iot747.com/download/iot747-standard-nda-form/), we can share the source code of the python script that does the DFY over UART. Usually we share with customers so they can integrate on their host processor. But in your case, you can run it on your laptop and modify it to use mmultiple UART and do parallel upgrades.
