If you're having difficulties establishing a Wi-Fi connection with the module, please contact customer support at email@example.com
If you're using a mesh network, make sure that it's using the WPA2 safety protocol and that you've enabled a 2.4Ghz band with its own SSID as well.
To check if your module is having difficulties communicating with your access point, please try provisioning the Wi-Fi through your mobile hotspot (iPhone users should toggle on the "maximize compatibility" mode).
PLEASE NOTE: If the module is in charging mode (plugged in) that can potentially result in failed pairing. So the module should be disconnected from charging while pairing at all times (but it's still important to make sure it has enough battery before you initiate the pairing process).
