Can you please post a schematic of your circuit. Statements like "From the 3.3v regulator with 5v or 12v actually running through it" make no sense whatsoever and actually makes me wonder if you actually know what you are doing.

Hi thanks for the reply I posted the image above and explained the pin connections, what I meant above was that 5v or 12v running through a 3.3v regulator (AMS1117 800mA). As in 5v or 12v VIN, through a 3.3v regulator and VOUT is roughly 3.24 ish. Seems fairly straight forward to me, not sure how that could confuse or why a schematic will provide any additional help to what has already been explained, but will post one below.

May not be totally obvious so the set up is as follows:

GND -> ground ( Wire soldered from pin )
VCC -> 3.3v / 5v also has a 100uf cap (Wire soldered from pin)
CH_PD -> 3.3v / 5v (10K soldered from pin)
GPIO15 -> GND (10K soldered from pin)
GPIO2 -> 3.3v / 5v (10K soldered from pin)
RST -> 3.3v / 5v (10K soldered from pin)

RX/TX -> TX/RX of programmer.

100uF cap on vcc / gnd

The regulator below is 3.3v, (Sorry this is currently a 5v regulator) as the programmer is both 3.3v and 5v there is no need to use it, but I have tested multiple 5v adapters through it without any success, this was documented in my previous posts, the only thing that would work was a 12v going through it. Multiple regulators have been tried.

Using 5v without a regulator works perfectly as does using the programmer in 5v mode.

I am definitely open to answer that would solve the need for 5v but as mentioned have not found one yet.

Here is the setup again mate.

Sorry forgot the reed switch, reed switch is connected to gpio5, at this moment is not.

With this setup it will not work, crashes, does not connect to broker, HTTP_UPDATE will not work.

Without the regulator and using a 5v input or the 5v input from the programmer, everything works correctly with no issues.
