Cant attain maximum throughput of 803kbps? with nordic DK kit and a Cellphone (ASUSX100D)

[Venket]

Hii ,

•      Iam using nordic nrf52832 board In the example of ble_att_mtu_throughput  example . I have tried a lot to achieve the 803 kbps, but the output was  204 kbps only. I worked with all para meters such as

          Central device --- Nordic nrf52832 

          peripheral ---- ASUS ZENFONE MAX M1

         Used application  ---- nrf CONNECT [ https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp ]

• BLE_GAP_DATA_LENGTH      =  320

• CONN_INTERVAL_DEFAULT  =   7.5

•  CONN_INTERVAL_MIN = 7.5 AND MAX = 500

• BLE_GATT_MAX_MTU_SIZE = 158

What else i can do increase the throughput?

Help me to get out of this .

Thankyou in advance for your help ...

Hello,

Attached below is a throughput test example I made to test the max. transfer speed. Can you try this and see if it gives you the same result? To perform the test you can open our android nRF connect app and enable notifications. The data transfer will then start, and the measured throughput will be logged over RTT.

Hello,

       I have downloaded and put the folder in the root folder of nrfsdk17.0 but when i try to open the main.c file  showing error like this "Cant read". What may be the reason ?

Hello,

Sorry, forgot to point out that the project must be placed \nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ to build. The relative source paths will not be correct otherwise.

   Still it not working the main.c file is missing..?
