Vmc_commands about mdb-arduino-cashless HOT 3 CLOSED

Hello :)
Some VMC doe reissue messages to make sure they are transmitted correctly - or if they are not aknowledged correclty.
So just ignore them if they are resend, or test if you dont aknowledge them correctly.
Do you get reset by the vmc from time to time ?

Thanks for you response.
When i issue beginsession command with available user funds, then sometimes vmc begins the session and show user credit on lcd but some times it ignores beginsession command so as i stydy in nama mdb spec4.2 that vmc does ack the sessionbegin command so i want to use that ack, nak, ret send by vmc to confirm that sessionbegin and if nak is received by reader then sessionbegin should be issue again.

i am not shure if i do understand correctly but yes, if vmc does not ack your session begin, you should do it again :)
we implemented as such, that the cashless device answers every poll with session begin, as long as the vmc did not change to session idle yet
