Currently, there is a project. The situation is that the master nRF52840 communicates with the cloud server through the GPRS232 module, the slave nRF52840 communicates with the master nRF52840，and the zip packages required by the master nRF52840 DFU and the slave nRF52840 DFU are distributed by the cloud. But I have n’t done any similar attempts before. The ZIPs required for DFU are distributed by mobile phones. Is there any solution or case for reference?
