Re: Antenna design

Yeah, it's a shame, I hoped I found some way to 'prove' antennas to be good or bad, but it seems OpenEMS is so finnicky that at least I cannot really use it for it.

Thanks, ChatGPT!
Fwiw, that account (unsurprisingly) was a spambot, so I nuked it and its message.

Re: Debug and flash program ESP32-S3-WROOM-1

Yes. It's advised to have a boot button (or other access method) on GPIO0 in case somehow the USB-serial-JTAG port gets accidentally disabled in firmware, but this is mostly something that is useful to have in case of an emergency, not something you'd use every time you flash the device.

Re: Debugging with UART

Well, you could use printfs and log statements, but if you're expecting to attach an external debugger with ease: no chance.

Is the internal USB-serial-JTAG connected or the GPIOs for that (12 and 13) available? If so, you could still use the USB-serial-JTAG device.

Re: Hiss in PDM audio output

What I mean is, can you zoom in onto the 'silent' bits so we can see the hiss?

Re: Antenna design

Hm, seems like the simulation is incredible sensitive to simulation parameters; you're right in that a higher cell density makes the resonance disappear but increasing the number of timestamps (NrTS) to e.g. 180000 makes it re-appear, even though the S-numbers are a lot lower than before. I'm decent...

Re: SPI1 External Flash Code esp_flash_

Yes. You define your partitions in the partition table which gets generated from a CSV file. In that partition table, each partition gets a name, type and subtype. The bootloader will only look at partitions with type=app (which is the same as type=0), so if you give your data partition a different ...

Re: any sdk support for amp on esp32s3?

I think Zephyr has AMP support, but not sure if that's for the ESP32-S3.

Re: ESP32 virtual network interface

This probably doesn't work as any Linux calls on that interface don't have an equivalent in LwIP (the TCP/IP stack ESP-IDF uses). Possibly you need to track down those calls and change them to their ESP-IDF equivalents.
