BLE Throughput

[kai19960504]

Hi All,

As far as I know , BLE Thrughput is basically set around a few parameters => 1. NRF_SDH_BLE_GAP_DATA_LENGTH

                                                                                                                            2. NRF_SDH_BLE_GATT_MAX_MTU_SIZE

                                                                                                                            3. NRF_SDH_BLE_GAP_EVENT_LENGTH

My question is => Does the value of NRF_SDH_BLE_GAP_EVENT_LENGTH represent the packets that can be sent in each connection interval?

According to this table : 

If the event length equal 7.5ms,does it mean that it can transmit 6 packets?

Best regards,

Kai

The content of v7.3.0 is like the picture when I asked the question, I don't understand what you said "Note that the documentation you refer to is for an old SoftDevice."

Hi Kai,

That was my bad. I did not realize that you only included parts of the table. I see now that this is the upper few rows of Table 1 under Bluetooth Low Energy data throughput in the latest SoftDevice Specification.

Hi Einar,

I have checked a lot of information, and it shows that many packets can be sent, but I can only receive up to 6 packets per connection interval. Is this correct?

[Einar Thorsrud]

There is no hard limit of 6 packets per connection event. If there is more data to send, there is time left in the event, and there are no retransmissions, you can send even more packets than that per event.

So,how to interpret this picture?
