CC2564CMSP432BTBLESW: HFP Profile Volume controls & Initiate client reconnect/Disconnect

Gokulnath A R

Part Number: CC2564CMSP432BTBLESW
Other Parts Discussed in Thread: CC256XCQFN-EM, BOOST-CCEMADAPTER, CC3200

My setup:
CC256XCQFN-EM
MSP432P401R launchpad
BOOST-CCEMADAPTER
CC3200 AudBoost

Code Composer Studio Version: 10.4.0.00006

BT Stack: CC2564CMSP432BTBLESW-v4.2.1.1 (I would really like to use 5.0 or greater Stack)

I would like to make few functionalities for my Work In Progress new product(HFP only I don't want to use HSP as my client is private & custom datasets for security purposes)
1) attend call/cut Call
2) Increase/Decrease Volume
3) Like to use unassisted modes as I'm already using External Codec and maybe would like to use a combination of few BT classic profiles as well HFP+SPP+AVRCP+A2DP together
4) Send custom one way(from by TI BT headphones to my client) ASCII characters Through HFP profile only how can I achieve this?
5) initiate Reconnect/Disconnect to the remote client(not present in the HFP as of now)

I have already tried the demo examples as here It all works great individually except solving a few of my needs like 2,4 as stated above.

Also, I would like to know how to combine all the above profiles together?
Correct me in any stages if I'm wrong
New to BT Domain & a rookie Coder. Thanks for your help & Time in Advance.

Hi Gokulnath,

For 2), can you try using the ChangeSpeakerGain API?

For 4), can you try running the APIs I mentioned in our last thread? Can you try using the RingIndication and SendCallerIDNotification APIs?

Do these work for you?

Best regards,
Jacob

Hello Jacob,
Thanks for the reply! (Also in the previous thread)

I'm now under the process of testing the 2) & 4) functions ...!
I shall get back once I'm done.

is there any solution for the no 5? Please let me know thanks!

Hi Gokulnath,

For #5, there are several API's depending on the functionality you are looking for. For example, you can call OpenClient to initiate a connection with a remote headset or audio gateway, or OpenServer to open a serial port server on the local device using the Head-set Profile.

Thanks,
Jacob

Dear Jacob,
Thanks for the assistance!
but is there a way to achieve the same result in the HFP profile? any already functions which is present of which I can use as a base for rewriting it ?

Thanks for your time in advance

Hi Gokulnath,

For HFP, you can try using OpenAudioGatewayClient from HFPDemo_AG and OpenHFServer from HFPDemo_HF. However, you may run into some difficulties managing a server and client with the same code.

You can check those out and let me know if they can solve your design requirements.

Thanks,
Jacob

Hello Jacob,
Hope you are doing well!

I have tested the Sendcalleridnotification API & Ringindication but unfortunately, I get this error

HFRE_Send_Call_Line_Identification_Notification() Failure: -1005.
ServerPortID : 1.
Function Error

How can i Eliminate this?

my use case is basically simulated Data sending via AT commands on top of Rfcomm via HFP.

I attached an example of 2 Bluegiga modules running Iwarp stack----- one as HFP-AG & the other as & its Terminal shown:

should I combine the SPP with HFP ? to use the function Datawrite in the SPP profile? (I don't want to open a separate spp port! I want to send the data via Spp port only!)

Just to be very precise:
I would like to send an event data just like mentioned below but the data is the custom one for our use case only through HFP?
The below example perfectly works for us.

eg.. "AT+XEVENT=HELLOFROMHFP, 1\r" which api should i use for this one in bluetopia stack ?

Mic / Headset will send the PTT commands via HFP link as follows:

PTT press down send out: "AT+XEVENT=TALK,1\r"

PTT release send out: "AT+XEVENT=TALK,0\r"

Please let me know the possibilities.
Thanks in Advance!
