expected BLE throughput on MAC

[klaus1234]

Hi

I have made a peripheral when I connect from a windows notebook I achieve around 800 kb/s.

According to this post 800 kbs is expected on windows machine.

On a Mac however I achieve only 600 kb/S. 

Is that also expected or shall I further try to improve parameters?

Thx

Hi, 

It might be due to macOS imposing different connection parameters (e.g., longer connection intervals, different ATT MTU negotiation, or fewer packets per connection event) compared to Windows. These host-side limitations are well-known factors that affect achievable throughput. See BLE throughput factors

You can use the nRF Sniffer to capture the sniffer log to compare the behaviors/negociated connection parameters with Windows/Apple.
