Re: Multiple ESP32 clients connected to a single server

You'll have to be a bit more specific than that: what protocol are you using? Are the server and the client on the same network, or does it also need to work if there's a NAT in between (needs a 3rd-party server)? How do you connect from client to server: is the ESP32 an access point, does it connec...

Re: ESP32-A1S and esp-adf

FWIW, ESP-ADF is not a separate SDK, it's a framework of audio handling and plumbing functions built on top of ESP-IDF.

Re: httpd_uri: httpd_uri: Method '2' not allowed for URI

As far as I can tell, 2 is HTTP_HEAD; Edge may be trying to get just the headers to see if the file changed vs its cached data. You probably haven't implemented a handler for the HEAD method, so the webserver is complaining.

Re: Using LEDC for generating two pulses

That is extremely slow... is there a reason why you don't just generate these pulses in software? The issue here is that the hardware possibly can go lower than 1Hz, but the Arduino HAL driver you're using only understands values of 1Hz or above. You could try poking the LEDC registers directly in o...

Re: Is eternal spinlock possible?

Can you explain a bit more about what you're trying to achieve? Are you trying to implement a protocol in software or something?

Re: ESP32: Power On status of the pins during power-on/ boot up process.

18 and 19 aren't used by the chip on boot as far as I know. Do you have pullups/downs on the gates of your mosfets?

Re: HC-SR04 using RMT - very fast

It possibly needs

Code: Select all

 rmt_config_t rmt_rx;
changed into

Code: Select all

 rmt_config_t rmt_rx={0};

Re: switch spi mode at run time

You can set the SPI mode per device if you use the ESP-IDF SPI driver. The driver will handle switching for you.

Filzek: Sorry, I have no idea what you're on about. Perhaps you want to start a new topic for this, with a bit more information?

Re: ESP32: Power On status of the pins during power-on/ boot up process.

You could try to hack the bootloader to set the GPIOs as soon as possible.... but that would be a workaround at best. What GPIOs are your mosfets connected to? Can you move them to IOs that aren't used during boot, and add a pull-up / pull-down resistor to force them to the correct level around that...
