Hello,

I have questions about BCM4343W/BCM4334W.

  • How many simultaneous BLE connections do these SoCs support? I mean BCM43xx is in Central role. We need to connect 21 Peripheral devices. Is it real?

Currently our configuration is:

    • - CPU Allwinner R13
    • - Linux, kernel 4.8.4, BlueZ 5.41
  • Minimum Advertising interval could be 20 ms in accordance with BT specification. Do BCM4343W/BCM4334W support such interval?

Thank you!

Best regards,

Artem Zemlyanukhin

I believe the limitation on simultaneous connections is dependent on the bt stack and on available memory. I will need to verify and get back to you on this.

Perhaps vsb​ knows more.

Hello,

is there any news on our questions?

I also have another question. Does BCM4343W/BCM4334W support peripheral and central roles simultaneously?

Best regards,

Artem

Are you working with a Cypress module partner? Have you engaged them as well?

This is supported under WICED for sure: 3.7.0 BLE: Simultaneous Central / Peripheral?
