Maximum data throughput.

[Jorge]

I wanted to know what's the maximum data throughput if one device has both roles (Client/Server) working at the same time. I already saw the tables for the different SoftDevices (s110, s120 and s130) but not sure if the maximums they display are for one way only or for the two. I want to use this so I'm able to full duplex audio transfer over BLE, but want to know what's the maximum data I can send/receive on both sides (Central/Peripheral). thanks in advance for your answers

S130 and S132 v.2.0 supports up to 6 packets per connection interval per connection, no matter if the device is central or peripheral. However, the minimum connection interval depends on the number of connected links.

For one connected link, central or peripheral, the minimum connection interval is 7.5 ms.

For two links, the minimum connection interval is 15 ms if you want to be able to transmit 6 packets per connection interval per link.

As you understand, if you want to be able to transmit 6 packets per connection interval, the connection interval has to be at least total number of connected links * 7.5 ms. The reason is that it requires some time to transmit packets over the air, and more packets to transmit, more links, require more time.

I found this question that he wants to change also to the High Bandwidth. I'm still not able to change the bandwidth to high, I think it has to do to the RAM, but not sure, if I have a solution to change to High I'll post here. From what I understood for the counts it's like this

{

uint8_t high_count;

uint8_t mid_count;

uint8_t low_count;

}ble_conn_bw_count_t

so it should be (high_count, mid_count, low_count) don't understand the default numbers either.
