File Transfer service in BLE

or

what could be the best way to transfer 200kb size file from master to sleave (nrf52) ?

Hi Karthik,

There is no dedicated file transfer service in BLE. If you just need a simple way to transfer data between two devices you contorl, I would suggest looking at the Nordic UART Service samples (Bluetooth: Central UART and Bluetooth: Peripheral UART). If you take those, but instead of sending data to/from the UART interface, read/write a file/array/chunk of data.

Edit: Another option is to use OTS, which is a standard service for object transfer (basically a blob of binary data). That is demonstrated by Bluetooth: Peripheral OTS and Bluetooth: Central OTC.

Br,
