I have been working on a Pos terminal app for Pax A930 device. I was able to AID, card type and etc but when i tried the GPO command, it throws 6985 error. I am not sure issues is from my end or whether the SDK got any issue.

Everything works perfectly upto here but when i try to execute the GPO
80A800000283000000
I get 6985
As per my knowledge i didnt get PDOL response from the 3rd call, so i am using the commonly used command for the GPO.
can someone guide me on this?
