Hi,
1- I want to know want the OTA firmware update, as I know with DFU we can only update firmware of BLE chip that is NRF 52480. But in my case, I want to update the firmware of my sensor microcontroller that is connected with BLE chip NRF 52480 through UART. How to do that?
2- How to use BLOB, is there any example?
3- In DFU, we need BLOB (correct me if I am wrong) but when I see DFU example ble_app_buttonless_dfu, their is no mentioning of blob. Please clear this confusion and answer my questions.
