Using the phone app, the phone can connect to the Gateway with bluetooth and NFC, however, it keeps saying "Gateway registration fail. Please try again" after a minute of waiting.
I'm thinking this might be due to a registration error. The first time I used the app and tried to commission the gateway, I was not able to perform steps 6. and 7. of the MGOOBDSUG.pdf which are:
6. For the first time log in, it will be required to fill out few details to register the NXP Modular Gateway.
7. An email will be sent to the email address with a verification code that needs to be added into the OTP field (One-Time-Password).
I did not receive an email with a verification code, but since that time, I was able to go to the Gateway Commissioning step where you scan the QR code and try to connect the Gateway to Wi-Fi. But it would always result in failure.
