Operation is very slow

My red mangoH with WP8548 is successfully complied with “make red_wp85”. I update the update file to the mangoH. There is an app called “redCloud”, is enabled to test the sensors. The sim card is already added to the AirVantage Cloud.
In my AirVantage control panel, I tried to set up the interval blink by LED. It seems like the command is pending for a long time. But some command is working such “Provisioning”. Something wrong? How do I remove the board and re add to AirVantage?
