Switching between wifi network modes.
Being able to switch into access point mode using M552 is really good however it could be improved by removing the requirement to switch the wifi network off first.
Currently you have to send M552 S0 then M552 S2 and once finished in access point mode M552 S0 then M552 S1. This means its not possible to do it all over the network. I even tried a macro but that did not work, probably because there was not enough of a pause between the M552 S0 and M552 S2.
