Re: ESP32 auto sleep?

The annoying thing is that the ESP32 is soldered on my PCB so it is difficult to add that module to usb (i don't have usb connectivitiy on my PCB). I have tested a little more and so far the modules haven't disconnected yet (since last week). If it does disconnect again i will try to figure out how ...

Re: ESP32 auto sleep?

Any chance you can get e.g. a Raspberry Pi to log the output of the ESP32?

Can you explain how? Via rx/tx?

I think i will be able to do that, i made a pcb so i am not sure if i can get alle the right connections but i may be able to find out how to do so.

What / how do i log to a raspberry pi

Re: ESP32 auto sleep?

Maybe the ESP32 is damaged? I am using this PSU: Mean Well IRM-03-3.3 I have connected more than only the EPS32, but tested with a lab power supply, the max current it uses is about 400 / 500 mA Connecting it to a pc is possbile, but the problem is that it could take many days before the fault happe...

Re: ESP32 auto sleep?

I just don't want to let it sleep. My question was if the ESP32 goes into sleep by itself without me doing that? Because it feels like the ESP32 goes into kind of a sleep mode with WiFi enabled but not getting a connection.

It could be something else but it feels like that

ESP32 auto sleep?

I have an ESP32 wrover module which seems to "fall asleep" by itself. Probebly it is something else but it looks like this. The module is connected to wifi and gets sensor data, sends it to a webserver and does this every X seconds. It also has an RGB strip to show some modes (blue light is normal, ...

Re: ESP32 set time offset

This doesn't make any difference, also it doesn't look like it is the timezone, i have a time difference of 1 hour and 43 minutes, it is not a full hour or 2 full hours

ESP32 set time offset

I want to load the time from my own server and set the ESP32 clock to the received time. The time from my server is a php script that returns this: <?PHP echo strtotime(date('Y-m-d H:i:s')); ?> The EPS32 receives the time and sets the internal clock like this: struct timeval tv; tv.tv_sec = atol(rec...

Re: 16MB Flash max app size with OTA

What do you mean with "Corruption of FFat is a much bigger one". When did you have corrupted FFat storage?

Re: 16MB Flash max app size with OTA

Thank you for the reply. I am planning on using the ESP32 in a production environment. Dozens, maybe hundreds of devices are going to be sold and when we have an update, they all download the BIN file from our server and start updating. If the update fails, it should restart, but if failing means th...

Re: 16MB Flash max app size with OTA

Oh okay, i understand now, but is 3MB max? Why can't it be 8MB * 2, or 6MB *2 + 3MB?
Where and how can the FAT be used?
