A quick update to the previous post (a long time ago now).
After syncing the number of handheld devices, downloading QR apps and printing off a load of codes we hit a major stumbling block! No 3g signal!
To be fair you could get a signal in certain parts of the school site, which was why we didn’t pick up on the problem straight away. But in our new building it is almost impossible to get 3g.
@infernaldepart got on the case of getting them connected to the wifi around school. This should be done for the start of the new term. So hopefully I’ll have more to update here in the new year!
