I am trying to make a video call using UC864-E/G module. In the FAQs the following is stated:
UC864-E/G module can support only its bearer and the customer should
implement the video telephony protocol (3G-324M) and its UI application,
UC864-E/G module can support SVD(Simultaneous Voice and Data) feature,
To setup Video call use this bearer: multimedia 64 kbps CS Data call (AT+CBST=134,1,0)
1- What is the proper procedure to establish SVD feature to make a video call using CS Data call?
2- How and where do I supply the 64K video bitstream to UC-864?
3- Is there any Application note etc available that explains the details?
1 – The procedure to establish a CSD call for video call is quite simple
2 – Once you get the CONNECT message after the ATD command, you can start sending the 64Kb streaming using the 3G-324M protocol
3 – There’s no application note for this functionality but you can find many documents about 3G-324M protocol in the net.
