Dear all,
We are developing software on a raspberry pi2 using a bluetooth USB dongle (by Cambridge Silicon Radio); we are trying to connect via bluetooth an Iphone 5 (IOS9.1) and drive it from the raspberry doing dial-up calls and so on.
All the configuration activities (scanning, pairing and trusting) work very well. We are able to send AT commands like AT+BRSF but we are not able to start a dial call using the ATD command because the Iphone don't allow a Dial Up Network profile using RFCOMM protocol.
Trying to send the ATD command on same profile of the other AT commands, the Iphone replies us with "ERROR" message every time.
How enable Dial Up Network profile? There is a special AT command or a setting to do in the Iphone?
Please note that our software on raspberry works correctly with other mobiles like Blackberry or Samsung Android.
We follow the flow of figure 4.1 of document Hands-Free Profile 1.5 :
RFCOMM connection establishment
AT+BRSF=125
AT+CIND=?
AT+CIND
AT+CMER=3,0,0,1
AT+CHLD=?
ATD33<...>7
Any help will be appreciated.
Best Regards.
Alberto
