Does DA14531 Support Enhanced GATT?

Hi there

Can I check if DA14531 supports Enhanced GATT? If so, how?
Also, how does the device support 3 concurrent BLE connections?

Thank you.

Warmest Regards
Richard

Hi

Hi There,

Thanks for your question online and for your interest in our BLE solutions. I would recommend first checking the UM-B-119: DA14585-DA14531 SW Platform Reference and section 1 and .2.4. Bluetooth Low Energy Software.  Please see Figure 2 BLE Protocol Stack Layers and table Table 3 da1458x_config_basic.h configuration flags.

CFG_MAX_CONNECTIONS :         

Determines the maximum concurrent connections supported by the application. It configures the heap memory allocated to service multiple connections. It is used for GAP central role applications. For GAP peripheral role it should be set to 1 for optimizing memory utilization.

The MAX value for DA14585/586 is 8.

The MAX value for DA14531 is 3.

You can also check the DA14585/DA14586 - DA14531 Multiperipheral Example . This example example demonstrates how a single peripheral can be connected to more than one centrals ( in case of DA14531 ) .

Thanks, PM_Dialog
