Re: Good approach to disable WiFi?

No, don't do anything:

Code: Select all

void setup()
{
}
You don't need to disable it if you haven't enabled it.

Re: Good approach to disable WiFi?

This is nuts. Don't initialise it. There's nothing to stop.

Re: Rebuild flash encryption/decryption in software

How I told. I want to send an encrypted file to the ESP over html (no https) or the user downloads its himself, like a firmware.bin. The firmware shall nobody use on foreign Hardware. Only my first installed Software has the key. The title is confusing, then. It sounded like you wanted to implement...

Re: Best practice to avoid wdt trigger

In my opinion you should just disable the task watchdog. It's there to ensure that tasks (usually only idleTask) aren't unexpectedly starved. If you know that lower priority tasks will always be starved, by design, then it doesn't make much sense for the watchdog to panic about it. With a big discla...

Re: Calling or initilising I2C from within a task

Try a larger stack size (eg. 4096).

Is anything connected to GPIO 40? Are you using JTAG? Does a different pin number change the behaviour?

Re: <15ms boot, project approach

I don't know how you get thoose numbers (8uA) , the most conservative approach I can think of is 2ms ON, 13ms OFF permanently, that is 12% of the time ON, so atleast 12uA, just asking Tbh I don't understand what exactly you're trying to measure. Is it between the red dots in your above image? The l...

Re: <15ms boot, project approach

After research, seems that ULP will need 0.1mA ,if I am not wrong then it is too much energy for my purpose. It will only be >100uA while it's running, but you'd normally only start the ULP periodically (eg. every 20ms) and a typical ULP program has a very short execution time, so the average curre...
