Over the air firmware updates + testing

[licalvin01]

Hello,

My name is Calvin and I am tasked with testing the NRF52840. I want to create my own development board for prototyping a project, but I do not want to keep plugging in to program. 

1. What components do I need to keep to do bluetooth FOTA? Are there simpler options to FOTA?

2. What development tools do I need to begin programming the NRF52840? Please link. 

3. Is there a good development board option with this chip allowing me to practice FOTA before I do my PCB design?

Thanks,

Calvin

Hello,

What components do I need to keep to do bluetooth FOTA? Are there simpler options to FOTA?

The main component is the nRF52840, a BLE chip that enables FOTA (Firmware Over-The-Air) via Bluetooth. The primary concern is flash memory, as the size of your application may require external flash if it, along with DFU support, exceeds the built-in memory.

I recommend using the nRF52840DK, which includes the nRF52840 SoC. You can follow the Developer Academy course, which covers the SDK, IDEs, and essential tools for developing with Nordic SoCs. There's a dedicated lesson on bootloaders and DFU, specifically in the "DFU over BLE" chapter.

Kind Regards,

Abhijith

Can you recommend alternative microcontrollers or development kits that support Bluetooth FOTA and have similar capabilities to the nRF52840, excluding the nRF52840DK?
