Hi,

I can't find the function in the HFP AF profile corresponding to sending a +CIEV command.

Hi,

As far as I know +CIEV is sent from the AG to HF

Yes. And I want to send a +CIEV command from my AG to the HF.

Hi,

Did you try "UpdateCurrentControlIndicatorStatus" and see what is happening in the sniffer logs?
UpdateCurrentControlIndicatorStatus calls HFRE_Update_Current_Control_Indicator_Status, If it did not work can you try using "HFRE_Update_Current_Control_Indicator_Status_By_Name" and see if it helps

Which sniffer logs?

Doesn't HFRE_Update_Current_Control_Indicator_Status and HFRE_Update_Current_Control_Indicator_Status_By_Name send a +CIND command?

Thomas,

Sundeep is right, the functions to use are HFRE_Update_Current_Control_Indicator_Status() and HFRE_Update_Current_Control_Indicator_Status_By_Name(); the HFRE_Query_Remote_Control_Indicator_Status() function is for +CIND.

Have you tried these API functions? Are you having problems with them?

By sniffer logs Sundeep is asking if you have taken an over-the-air trace, i.e. a sniffer log, of the data transfer? Do you have a Bluetooth sniffer, for example a Frontline or Ellisys sniffer? If you do have one, and you are still having issues, please record an over-the-air log when the problem occurs and upload it here so that we can have a look and determine what is wrong.

Thsnks,
Samuel

Hi Samuel,

According to the docs the HFRE_Query_Remote_Control_Indicator_Status() function is for HF only (so it's for AT+CIND not +CIND).

I tried the HFRE_Update_Current_Control_Indicator_Status() with CALLSETUP 1, but the headset doesn't seem to be aware of this. If I press the headset button to pick up nothing happens (no events received).

I don't have a BT sniffer available, but I have a CSR dev kit for which I made a headset application. I'll try tomorrow to connect to that and see if I can log the AT commands it receives.

Hi Samuel,
I've verified that HFRE_Update_Current_Control_Indicator_Status_By_Name() sends a +CIEV.
Thanks!
