BLE DFU boot loader and device information

Sorry, what I meant to ask was if it is even possible to upload the wrong FW? It will *not*be if you have configured them with different HW IDs.

These devices are going to be in the field and have different behaviors i.e. different product verticals and feature sets, different workflows for subsequent DFU OTA updates, etc.

The product firmware that runs on a nRF52832 platform is very different from the version that runs on the nRF52810. We do not have the luxury of mismatching the firmware and the hardware.

How can the BLE application that manages the DFU workflow retrieve this information from the target that it is to be updated.

Hello,

There is a Firmware version command request available in the DFU transport, but it is disabled by default through the NRF_DFU_PROTOCOL_REDUCED setting. What happens if you upload the wrong update package, will it be rejected? Also, are they both programmed with the same NRF_DFU_HW_VERSION?

Best regards,
