Valve is preparing the ground for its official arrival on iOS and Android mobile devices. This can be seen in the movements of the Steam Controller, which will now have the Bluetooth Low Energy connectivity, which will serve to pave the connectivity with the Steam Link.
About a week ago, Valve itself announced the new beta version of its Steam client with compatibility for the Nintendo Switch Pro Controller, now the compatibility with the controls continues to be improved and the improvements for your Steam Controller.
It can be activated from the Steam beta
This new feature has not yet been officially released despite Valve's own announcement, but can be activated from the beta version of the Steam client. This requires the controller firmware update and this in turn will remove any previous pairing of our controller. Once we have the BLE activated, we can switch between the two modes easily with the combination of the designated buttons.
Possibly and since it is a beta version, we may have some specific failures or problems so we don't have to draw negative conclusions from it either. In short, it is one more step towards the arrival of the compatibility of the Steam system with mobile devices that have the iOS and Android operating systems. Hopefully they don't take too long for their official release, but this is something that does not have a set deadline, although it seems that they are progressing at a good pace.
Apparently, it is a super comfortable control, I have not been lucky enough to try it, but from what I have been told it is very comfortable and practical.
