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,
Juliet Zhu
