Transmit Large Data 518222

user2677

Hi!

I have a Nordic nrf51822-DK. I'm need send large data to the Android phone (10 mb). I'm use sample devzone.nordicsemi.com/.../dealing-large-data-packet-s-through-ble , but speed very low (one minute passed 10 kb).

BLE can transmit at speeds of up to 2Mb (www.nordicsemi.com/.../nRF51822).

How speed up data rate?

    Hi Hakon,

    I need to send large amount of data from server to client in minimum possible time.

    Can you please tell me how can I send exact 6 packets (6 calls to sd_ble_gatts_hvx) per connection interval?

    Is it something you just mentioned as an example?

    I have gone through Ole Code Snippet but have some questions:

    - what is m_rr_interval_enabled and its use?

    - When is BLE_EVT_TX_COMPLETE event raised?

    Let's say, I have an array of 1024 bytes which I want to send into 64 chunks of 16 bytes (assume characteristic has length of 16 bytes).

    Should I just call sd_ble_gatts_hvx 64 times?

    When is BLE_EVT_TX_COMPLETE event raised in that case?

    Thanks
