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,

Hello,

[quote user=""] when I put it in DFU mode, does the connection break because I do send mtu response 30 seconds after the nordic replay[/quote]

Sorry I am bit confused. Were you able to put the device in DFU mode and it's breaking? Or are you asking whether the connection could break because of the MTU response?

Kind Regards,

Hello,

[quote user=""] How should I develop the software to put the nordic device into dfu mode via esp32?[/quote]

I haven't worked with ESP modules So not sure from that side. But from the Nordic side, you can enter the DFU mode by writing to General purpose memory retention register (GPREGRET).I guess you need do this from the ESPmodule, this will trigger a device reset and nRF deice will remain in DFU mode. Take a look at the Buttonless secure DFU section in the nRF5_SDK. This section (to the end) also explains how you can add Buttonless secure DFU service to an application.

I need to go through your old thread for answering the question 1 and I will get back to you after doing that.

Kind Regards,

Abhijith
