Hi,
We do not have any examples for ESP32, and generally few DFU master implementations. I wonder which SDK and DFU protocol and transpot you are using, though? There are some unofficial third party libraries for some, like this one for serial DFU with the old nRF5 SDK bootloader. It will requier work on your end, though.
I’m using the NRF Connect SKD 2.5.1 and I have it working where I can do an DFU by BLE with my phone and the NRF app but I basically want to replace my phone with the ESP .. kinda just need to know about any functions or something to put the Nordic to DFU bootloader mode or something I see a lot of samples using the old nrf5 SDK
I see. What I linked to before is not relevant for the nRF Connect SDK. And your ESP is supposed to also do this over BLE? If so, you likely need an SMP server implementation for it, using Bluetooth LE as transport. I am not aware of any such implementation for ESP (though that could exist, and you may find more infor about it in ESP forums). If the target was nRF, you could have looked at GATT DFU SMP Service Client.
