Hmm they only context I know it is in context of test automation as "Hardware in the loop". Apply nightly firmware to ble-perpheral via ssh- Install nightly app build on mobile via adb- Test ble connection - Test ble bonding- Test interaction between the devices- control some relais to trigger certain events- curl to see if events land in backend....

would be tedious to do it manually. That said everyting is in git...
