- Adds MQTT command to change the WiFi access point.
- Adds MQTT command to change the MQTT broker and update username and password.
This will test the connection changes first and, if unsuccessful, fallback to the current connection.
If successful the new configuration will be saved in non-volatile memory.
This adds the ability to specify if the MQTT broker connection is secure via a checkbox on the config page of WiFiManager.
Also added to the WiFiManager config page is a text box to enter the brokers TLS certificate.
In the case of using manual configuration a new macro is created MQTT_SECURE_DEFAULT.
When defined as true a secure connection will be requested and the certificate defined in user_config.h will be used.
If enabled in user_config.h this will trigger the OMG to update it's firmware from the link
provided in the MQTT message.
Example message:
{\"version\":\"test\",\"password\":\"OMGPASSWORD\",\"url\":\"https://github.com/1technophile/OpenMQTTGateway/releases/download/v0.9.6/esp32dev-ble-cont-firmware.bin\"}
If the firmware version in the message is not the same as the current OMG version the device will self update using the link in the url of the message.
Using NimBLE requires less resources than bluedroid so it is much less beneficial to
deinitialize the stack. Instead this initializes it once in initial setup and only deinitializes
before entering deep sleep.
