Through put test

[chetanhiremath]

Hi Team,

I have read in nordic documents that BLE 5.0 will have 1.4 Mbps of through put.

But when i am testing the through put example with my nrf52832 board, i am only getting 270 - 320 Kbps.

Please let me know the exact through put i can get practically?

Regards,

Chetan

Hi Chetan,

Which SDK and Softdevice version are you using?

Are you testing with the "ATT_MTU Throughput Example"?

What application are you running, what have you enabled?

 

Yes, it is possible to achieve "at best" 1.4Mbps throughput in BLE 5 with 2Mbps enabled.

Hi Martin,

I am using SDK v15.0 and softdevice S132 and example i am using is the below one

nrf\nRF5_SDK_15.0.0_a53641a\nRF5_SDK_15.0.0_a53641a\examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput

Please let me know whether its the right example or not?

Thanks and regards,

Chetan

Hi Chetan,

The default setting for NRF_SDH_BLE_GAP_DATA_LENGTH  (found in sdk_config.h) was changed from 251 bytes in SDK v14 to only 27 in SDK v15.

Solution:

Set NRF_SDH_BLE_GAP_DATA_LENGTH  back to 251 to fix the issue.
