. We open the wireless network on the PC, find the wireless network with SSID starting with "EBT" (e.g.
EBT_9BB311), and click "Next" to connect. (Here "9BB311" is the last 6 bits of the module MAC address, different
modules have different MAC addresses, so different modules have different factory SSIDs)
⑤.
After successful connection, the LED1 on the module base board is always on (GPIO9 is pulled low) and the PC shows
successful connection, otherwise, please operate the above steps again.

AT command mode to realize the subsequent bi-directional communication between the PC and the module)
