Calculating Max Concurrent Connection for Central with a given max BaudRate Per Connection

[Unknowncoder]

I need to calculate the max number of concurrent connection Central can support given the following

1. Connection Internval = 7.5ms
2. Baud Rate per connected peripheral: 3072Bytes per second (3KBytes ever 1 second)
3. Softdevice: S140
4. Only 1 Packet can be sent per connection internval. (Limitation in our software) This means that in 7.5ms only 244 payload bytes can be sent (I.e Max ATT value).

I know the S140 can support 20 concurrent connection. But can it support 20 when every connection needs to maintain a baud rate of 3KBytes per second. So image all connected peripherals are sending data at the same time, they all need to send 3KBytes in 1 second.

I don't understand how these concurrent connection will operate relative to the Connection Interval. For example will peripheral 1 transmit for the first 7.5ms, then peripheral 2 will transmit for the second 7.5ms, is this what will happen?

Hi.

Seems like this should be possible.  

You can use the online power profiler to get more information about throughput etc. with different connection intervals and other settings. 

The online power profiler can be found here:
