Heltec Lora 32 V3 Display Timeout #172

Closed g3cwi closed 1 month ago

g3cwi commented 2 months ago

Hoping to save power I set my display to switch off - but it remains on all the time.

Not the solution to your problem, but to put some perspective on how much can we realistically gain by switching the OLED display off. Based on excellent measurements on https://bitbanksoftware.blogspot.com/2019/06/how-much-current-do-oled-displays-use.html , the 0.96" 128x64 monochrome OLED that we typically run on our Lora devices has an average consumption around 8mA at 3.3V. This translates to approx 2mA on a 12V solar system.

Is it really worth switching it off?

Edit: on this level of power saving we should look at the power consumption of various LEDs on the board, suddenly they aren't trivial anymore in comparison to the display.

The display feels warm to the touch - but maybe that's components inderneath it?

On your device the LoRa radio SX1262 is under the display.

i made a few mods to the igate firmware to solve some HELTEC V3 oled not working

please test if you can.

g3cwi commented 1 month ago

Tested the latest igate firmware. The display is now back on (fixed) - thanks. The display and Wifi timeouts are not working at the moment.

added a WIFI KILL Switch (on Wifi AP section of webUI config)

this is to kill Wifi and WifiAP completely from restart for pure Remote Digirepeater which should lower power comsumption a lot (as we need for this special cases)

please test it a comment
