Large Data Transfer over BLE

[Keval Soni]

Hello,

I want to transfer a large file (approx. 1.5MB) over BLE using nRF52 Module in a way where BLE Host and BLE Controller will be on the nRF52 SoC and the application will be running on an External MCU. Both the controllers will be connected through UART.

Do you have any solution for the above-mentioned scenario which includes no change in the FW of the nRF52 SoC?

I believe you're looking for the Serialization library.

[Keval Soni]

Yes, thank you for your response.

I have studied serialization and found out that I can dump a pre-compiled code in the nRF52 chip and I can send BLE operation commands to nRF52 using an external MCU over UART without touching the code in nRF52.

HI,

You can base on my example github.com/.../nrf52_ble_transfer_jpg approach as reference.  request to get data with software flow control.
