S132 Maximum data throughput

[lynn]

We have a medical products need to evaluate the maxinum transmission data rate of BLE .i am using is the latest nRF5_SDK_15.0.0_a53641a.

i find to using the ios lightbule app transmiss one packet of data length have 185 bytes , i do not know the two BLE connection event between how many packets can transmit data?

how many is the Maximum data throughput?  how to test validation?   Is there any related demo project in the SDK?

Hi, you should check out the ble_app_mtu_throughput example in the SDK: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/ble_sdk_app_att_mtu.html

Maximum BLE throughput is a bit complicated and is a combination of:

• The physical data rate in bits per second,
• how many bytes you are allowed to send in one packet,
• how many packets you can send per connection interval
• and the connection interval.

All the chosen parameters also have to be supported by both the central and peripheral.

For more details I will recommend to read this article: https://www.novelbits.io/bluetooth-5-speed-maximum-throughput/
