Hi,
We are working on a application using the STM32WB55 and are using the P-Nucleo boards. We want to have multiple (5-8) servers connected to a single client and with a low latency and the highest throughput possible.
All servers are sending data with Notifications, both DLE and 2M is enabled.
From the testing we have done it seems that the Client gathers data from one client at a time. With 5 servers and 7.5 ms connection interval it results in a minimum latency of 30 ms, which in our case is too high. This also splits the throughput in half for each server connected.
Is it possible to have a system like the one proposed here on the Nordic Forums? https://devzone.nordicsemi.com/f/nordic-q-a/44762/ble-multi-link-high-throughput-lowest-latency
Nordic claims that it can support at connection event of 2.5 ms which results in data from 3 different devices in a connection interval of 7.5 ms.
Do you have a minimum connection event length? and is it possible to receive data from multiple servers this way?
How can we get the highest throughput for multiple servers?
Best regards,
Robert
