You may consider trying an official espressif development board to test pcb antenna performance which uses an espressif module that is mounted properly with the antenna sticking off the board.

No these are menuconfig options in esp-idf

Can you give more details about the hardware used? There are a lot of third party modules and boards I wouldn't really trust the matching and impedance control and coupling of the pcb antenna.

Even number of bits. Numeric value will always be odd. Value 7 has 3 set bits but value 15 has 4 set bits.

Hello, Is it the case that you had "encrypted" flag set in front of "nvs" partition in your partition table? If yes, then please refer to fix and linked issues in the commit https://github.com/espressif/esp-idf/commit/e2fb582cf85cfb3cde0fb6c038fbf566b64adfcd. This may help you. Thanks. He wants the...

That's not a bug? As I said, the original ESP32 has 4MiB of address space for mmap()ping things, but as the rodata and non-iram instructions are also mapped using that space, you're left with less actual space free for user mappings. Esp32 is supposed to have 12mb of irom mapping plus 4mb of drom m...

Nope. The ESP32 has 4MiB of address space for this. Some of this space is used for mapping your application code into (size depends on your application; it's always smaller than the size of the application binary, though). The rest is available for you to mmap() into. Was this issue of 3mb limit ev...

Interesting question because flash encryption already uses a tweak key and operates on 32 byte blocks. Maybe so pre generated partitions are still possible within the flow of secure boot and flash encryption. Otherwise you would have to generate and use flash encryption keys off device or the bootlo...
