Hi,

Can anybody tell me what is the best practice to troubleshoot EFT POS communication failures with MPOS? Currently I am having ' Received illegal character. expected ACK, ENQ or NAK. As I see it, the device sends ENQ and receives data that it cannot interpret as neither ACK or NAK. Can this be caused by incorrect hardware profile connector setup?

Thanks & Cheers,

Cyrille

Hi Cyrille,

It looks like you are working on custom payment connector. I will leave this question to other community members (developers) to answer. Let's see if anybody has experienced the same and can advise for you anything.

Thanks,
