Syncing between Ergdata and PM5

[ILambert]

It is happening more and more. All connected, recording properly, both screen show the workout. Press menu, all appears to go through and sync. properly BUT later I realise it is not on the Ergdata logbook.
Is there any way of transferring the result from the PM5 to Ergdata without having to hook it all up to a computer?
Becoming a real nuisance and happening randomly!
