DA14531 Data Length Extension

Hi Dialog,

I wanted to transmit large amount of data by DA14531.

Is DLE (Data Length Extension) supported by DA14531?

Furthermore, is there any data transmiting API in SDK?

Thanks

Hi tjuzzjj080412,

Hi tjuzzjj080412,

Yes, Data Length Extension (DLE) is supported by the SDK6.0.12. Please check out the CFG_MAX_TX_PACKET_LENGTH and the CFG_MAX_RX_PACKET_LENGTH macros in the da1458x_config_advanced.h header file. The default value is 251 bytes, which is the max value according to Bluetooth LE specification. You will not need to call any API for the DLE feature. Please notice that both Central and Peripheral must support DLE feature. If yes, the DLE will be decided automatically between the Central and the Peripheral.

Thanks, PM_Dialog
