Buttonless Ble DFU update via Esp32

[erifat]

Hello

I want to do buttonless dfu update via esp32. My previous problem persists. Attached is the link where I explained the problem.problem link.

I have a few questions;

1) While I have the problem in the link, when I put it in DFU mode, does the connection break because I do send mtu response 30 seconds after the nordic replay?

2) How should I develop the software to put the nordic device into dfu mode via esp32?

Best Regards

Hello,

AFAIK, we don't have a dedicated sample showing an OTA DFU from another microcontroller or BLE DFU server (in nRF5_SDK). Please take a look at this old thread from my colleague, please refer to the links mentioned in that which will give you an idea or starting point for this.

Kind Regards,

Abhijith
