https://devzone.nordicsemi.com/f/nordic-q-a/128785/expected-ble-throughput-on-macHi 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. devzone.nordicsemi.com/.../typical-throughput-in-ble-2m-phy On a Mac however I achieveen-USTelligent Community 13Thu, 23 Jul 2026 18:52:56 GMThttps://devzone.nordicsemi.com/thread/569431?ContentTypeID=1Thu, 23 Jul 2026 18:52:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3cc6f9ec-d084-49ac-b761-0a92841d1832Amanda Hsieh<p>Hi,&nbsp;</p> <p><span>It might&nbsp;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.
