Hi,
I'm trying to do DFU on a custom designed Bluetooth peripheral device using nrf connect for mobile application. I can able to perform DFU successfully is some mobile phone but with other mobile phone I'm getting GATT CONN TIMEOUT error.
If I can able to achieve the DFU through one device, what could possibly go wrong in other device.
I'm attaching the image of log below. please provide me with the possible solution.
