Hi Simon,

there is no way to force a certain MTU size via the QT API. AFAIR you cannot force it anyway as both sides can make requests but not demands.

Do you know if it is possible to set the MTU from the Qt side ? I am receiving bluetooth messages of size between 240 and 244 (max payload) (by notify). I would like to receive only messages of size 240. Is this possible ?

Best regards,
