How to upload the application code via BLE from Android device?

[Rajat]

Hi Everyone

I am using BLE for NORDIC UART SERVICES. I want to update my code via BLE instead of a USB or J-LINK.

How can i upload my code from the Android device to nrf52840 which is using s140 device and sdk15.0

Do i have to generate a package file or Can i upload the hex file of my code directly onto the nordic nrf52840 ?

If i have to generate the package and enable the DFU Service, Can i still continue to use my NORDIC UART SERVICE  inside the same code?

What is the process i need to follow to achieve the above requirements?

Thanks !

Hi Rajat, 

 

Yes you can. You just need to use our BLE DFU bootloader. You will need to generate package file. Please follow this link . 

Currently we don't have background DFU. You would need to switch from your main code to the bootloader mode and update firmware in this mode. 

You can send a BLE command to switch from your application to the DFU bootloader (Buttonless).
