Is there example OTA DFU code for nRF51822 in 2.4 GHz mode (not BLE)?

[Guilherme de Paula]

Hi all,

I've successfully used the examples for:

1. OTA DFU for nRF51822 in Bluetooth Smart mode.
2. OTA DFU for nRF24LE01 (2.4 GHz mode only).

But I couldn't find OTA DFU example code for nRF51822 in 2.4 GHz ESB mode (not BLE). Is there such examples?

If not, I'm thinking about taking the example DFU code for the nRF24LE01 (ESB) and porting the flash access functions, etc to nRF51 equivalent calls. Would that be a good approach?

Thanks!

Gil

There's no code example for the nRF51 family for using 2.4 GHz to do a OTA DFU. You have to take into account the interrupt forwarding that's happening to the bootloader. I would recommend to have a look at the code example for the UART based bootloader without S110. Then you have to replace the UART traffic with 2.4 GHz as transport instead.

Hi Asbjørn, Thanks for the response, I've downloaded the latest SDK from the website, but I can't find the UART-based bootloader without the S110 Soft Device. I could only see the ones that use BLE/S110. Maybe it's on GitHub? Could you please point me in the right direction (a web link or the path in the SDK folders)? Thanks again. Cheers, Gil
