1. Device Online

At this time, the module equipped with the program has started to run, and you can view the program on REPL page. REPL is used to communicate with the device at the PC end and issue commands to make the device work according to the developer's idea. At the same time, the device can return information to the PC, and the user can see the internal operation of the device in the interaction interface. When event: 2 0 is displayed on the interaction interface, it indicates the module has connected with Developer Center. The interaction interface of QPYcom is shown as follows.

At this time, you can see the device is online from Developer Center. The presentation of Developer Center interface is shown below:
