How can I connect two nRF52840 to transfer large data files?

[Gerry]

Hello, Would you have application that can support two nRF52840 pairing and transfer arbitrary large data files?

Thanks, Gerry

Can you teach me to do this ?

The packet transmission is handled by the function called char_notification_send(..) on line 218 of amts.c
Right now it is only sending a static buffer called uint8_t data[256] over and over, but you can replace this variable with some data of your own. The "file" size is set by the AMT_BYTE_TRANSFER_CNT define, which you can also change if you want to change the transfer size.

The transmission of dummy data is initiated by the nrf_ble_amts_notif_spam(&m_amts) function. You should probably add a similar function that allows you to pass some data to the amts.c module, rather than just sending dummy data, and have the char_notification_send(..) function break your data into pieces and send them one after the other.
