throughput

but in novel bits its stating that multiple packets per connection interval and then they calculate the throughput. kindly tell how to use it in my case to find throughput

Sorry, but you have the information you need in the provided link and description. You need to study the BLE examples in the nRF5 SDK.

If you send 29bytes every 100ms then the throughput is: 29bytes / 100ms = 290bytes/second.

Best regards,
Kenneth

can you pls tell how much will be my throughput if:

like if i have 29 bytes of temperature humidity data

23.17 44.90-01/01/70-00:00:19

i took 10 readings like this

i have set connection interval as 100-100ms

how to get throughput with ble 4.2 and ble 5

The novelbits.io article you refer to is very good. You can also find some theoretical throughput numbers here for various configurations:
https://infocenter.nordicsemi.com/topic/sds_s132/SDS/s1xx/ble_data_throughput/ble_data_throughput.html

One thing you should be aware is that in most cases the link will be established with some default parameters, and then the central and peripheral need to exchance various feature exchanges (e.g. attt mtu, dle, rf phy, connection parameters) that will enable the higher throughput numbers. So you will not get high throughput before this have occured. If you open an BLE example project you can find this is typically configured/handled in gatt_init() and conn_params_init().
