HI,
I have couple of questions here.
1.Is there any sample application that upgrade firmware over BLE using zephyr/NCS 2.1.0 for nRF52840
2.If so our requirement is as below.
nRF52840 connected over SPI to another module(which has its own firmware). We need to download the nRF52840 and the other module firmware over BLE and upgrade both
How this can done?
3.How we can secure the BLE firmware upgrade to avoid unkonwn firmware upgrade
