Change BLE communication setting

Please tell me how to change the communication data length of BLE communication to 244 bytes and shorten communication cycle. Thank you.
I am using the version of [nRF5_SDK_15.0.0_a53641a].
Functions for BLE communication differ depending on the version, "ble_nus_string_send ();" in [nRF5_SDK_14.2.0_17b948a] but "ble_nus_data_send ()" in [nRF5_SDK_15.0.0_a53641a].
Please tell me how to set [nRF5_SDK_15.0.0_a53641a].
Thanking you in advance.

  • Hi Yokokawa, 

     I am sorry, but I do not understand Japanese. I took your first sentence in "google translate" however and I think I got the meaning of it.

    "Please tell me how to change the communication data length of BLE communication to 244 bytes and shorten communication cycle. Thank you."

    Please check out the "ATT_MTU Throughput example" in the SDK, and use that as reference on how you can change these parameters.

     

    For your second question, I would recommend you to look at the "ble_app_uart example" to see what is the correct way for the SDK v15.

     

    If I have misunderstood something, please let me know.

     

    Best Regards,

    Martin L.
