STM32WB55 How to improve data throughput?

[Lep]

​The following figure is the load and corresponding interval of my single notification：

I think the interval is too long.I read AN5289 7.6.5 how to maximize data throughput, but I can't find the macro parameters Min_CE_Length and Max_CE_Lengtht, and I don't know where to insert these functions into the program.

what are you using in the reception side? a phone? another stm32w?

I found out there are huge differences between archiveable data troughput between BLE devices (and SOs).

Another stm32wb(USB dongle) is client, my own board is as server.

Hello,

You can manage the CE_Lenght parameter using aci_gap_start_connection_update command.

Best Regards

Thank you, in fact, I have tried these a long time ago, and it has never worked. What I found that finally got me success was I added this command: hci_le_set_Data_length();
