Hi,

I am using Cypress CYW4343 chipset for a PoC with i.MX6UL-EVK for a Bluetooth application. We are able to create a GATT profile over LE connection using pyBluez and the communication is happening perfectly, but the bottleneck is the speed. For which we are trying to understand if we could utilize the GATT server over EDR as the chipset supports BR/EDR/LE.

In the attached Bluetooth SIG document, we see that optionally the GATT role configuration is possible over BR/EDR.

I am a bit confused about this configuration. Can I get an insight on that, and if this is possible, we would like to use it for our development with CYW4343 or CYW20706.

  

Thanks & Regards

Hi ,

As per BT spec, there is an option for opening GATT over BR/EDR connection. In WICED , we have the API wiced_bt_gatt_bredr_connect .

In that case, wiced_bt_transport_t  of wiced_bt_gatt_connection_status_t  should result in BT_TRANSPORT_BR_EDR

As per my knowledge this is not used in any profiles currently. So this option can't be used for current applications.
