Tab5 / UIFlow 2 / M5UI & MQTT (V2.4.2) #85
Description
M5UI / missing feature: You cannot set the screen brightness (hardware) - but in M5GFX you can.
MQTT / connection issues: MQTT loses its connection every 30 seconds or so. I have to check the status in the main loop and force to reconnect every time - which also takes some seconds. The same application runs on M5Stack Core2 (UIFlow 1) without any interruptions or issues.

mqtt_client.check_msg()

@bh4vd5qvzt-cmyk mqtt_client.check_msg() will proactively reconnect to the MQTT broker.

Hi. There is new UIFlow2 V2.4.7, where many bugs have been "silently" fixed (my problem has been fixed, too).
Please upgrade your device's firmware to V2.4.7 and test again.
