Dual COM port support in Bluetopia V1.2

Hi,

Moving it to SSO team for precise answer

Hi,

If you look at the code for SPPLE demo, we have support for multiple SPP(BR/EDR) connections in there. You may use that as your base code. Please take a look at this wiki as well. http://processors.wiki.ti.com/index.php/CC256x_Bluetopia_Software_Add-on:_Multiple_SPP_Connections

Please note that the sample code in the wiki is deprecated but the functionality is the same.

I am configuring my TIVA as Server with port-1 and port-2 open. Both the ports are opened successfully using Bluetopia SPPLE example.

Can 2 Android devices [Clients] connect to this TIVA server simultaneously and exchange data?

When I try to connect with 2 Android device simultaneously, I got these logs.

"Malloc Failed: 1024."

But,

If I try to connect to Port1 and Port2 from Different android mobiles one after the another, there is no issue.  It transfer the complete and and works well.

Is there any known issue in Bluetopia where more than 1 port should not be used to communicate simultaneously?

HI SSO,

I got the solution for above mentioned issue.

Now I have another query.

To have 2 ports working in parallel,  should I configure my TIVA as master using role switch option?

is it mandatory ?

Hi,

Role switch to master is mandatory for multiple connections.

But may I know why please?
