Hi, I'm developing CYW20706 Bluetooth chip.
I have some questions.
The CYW20706 is connected to android smartphone.
There are installed VoIP applications such as Skype, Whatsapp and Viber in android smartphone. (except iPhone)
I would like to receive incoming call via VoIP using CYW20706.
When a call is incoming via VoIP, the call state of CYW20706 is displayed outgoing call.
I can't understand this situation.
The incoming call is good in general call situation.
But the incoming call via VoIP is problem.
When the call via VoIP using CYW20706 or general Bluetooth chip is incoming, Why does the outgoing call displayed?
How do I change the outgoing call status to incoming call?
Can I change the call status using AT command?
I attach the log about this situation.
