Over the air bootloader

[Bikkel]

Dear support,

We are in the design stage for a BLE application. We looked at different options. Although the NRF51822 seems better in specs. The TI parts CCxx offer this bootloading over the air option which is very attractive to us as we can skip some hardware parts like USB connector etc. Are there developers busy with a Nordic solution which uses over the air bootloading ? Is this technical possible ?

is this function atrractive? in my oppinion,the specs are more important.

[Bikkel]

Yes it is very attractive. With over the air bootloading you do not need any cable connectors saving on hardware and make the device more simple. No extra hole in the hardware for a connector like USB etc. This make upgrading in the field so much more user friendly. Also is it a bit weird I think, you plant a BLE chip on the PCB with the purpose to go wireless. No when you want to upgrade you need a cable again. Can it be done in the NRF51822 from a technical point of view ?

It is most definitely technically possible to do a BLE bootloader for over-the-air firmware upgrading, but currently the only option we have is the experimental UART bootloader included in SDKs 4.3.0.

If you need to know for sure about future developments, you should contact your sales representative.

My Sales representative, did not understand what the word bootloader means that's why this question ended on this forum. If it is technical possible I could develop it myself, unfortunatully I'm not as smart as the people in Trontheim.

It's absolutly actractive. Fundamental and disruptive.
