NRF51822 file transfer over LE

[Jussi Vepsäläinen]

I need to transfer few kilobytes of data from slave device over BLE when requested from master device. I tough there is no file transfer profile in LE? What are the options to transfer file over LE?

Hi Charles

Thanks for your answer. Is there any examples of option 2 what can be used as an reference? And what is maximum payload data per one attribute? Somewhere was mentioned that value lenght is variable max 512Bytes but effective is much smaller?

Thanks for your support
