OTA from one nRF51822 to another.

[Eirik Aa]

Is it possible to do OTA from one nRF51822 to another? Is so how, and is not why?

I am using S120 and S130 for my applications and would like one device to uppgrade another if possible. This would be helpfull to roll out HW faster and uppgrade SW later.

Hi Eirik,

It's possible. However, we don't have an example for that.

The closest one we have is the python script provided at \examples\dfu\ble_dfu_send_hex in the SDK. Where we use the Master Emulator (the Nordic dongle) to update the firmware from PC. The Master Emulator runs on a modified version of the S120.

What you need to do is to follow the documentation of the DFU protocol and implement that on a S120/S130 application.

You can also have a look at our nRFToolbox app source code, to get to know how we do that on Android and iOS app.

i am also trying to do the same, updating firmware from one nrf to another, but i could not find the ble_dfu service for sending purpose, ble_dfu sevice present in sdk is for receiving puroses. so if you have found any solution for this, then please guide me. Just tell that from where i can get ble_dfu sevice for sending hex file part

We hired a company to write this for us. But look on the phyton example for sending.
