Re: WROOM-32 + external SPI devices

Yes. In theory it's possible to support other generic SPI devices over the flash SPI bus, but esp-idf does not have support for that yet.

Re: TG1WDT_SYS_RESET

Are you sure send_buff_size can't be bigger than 320*240*2?

Re: Robust method to receive data from UART?

I don't know, I don't see any glaring errors in your code, if any. Do you also only get one event with the 2nd 70'ish bytes of data in it?

Re: ESP32 - Content of internal ROM

Mostly the lower-layer parts of the BT stack (size-wise these occupy most of the ROM, iirc), parts of Newlib, some control code for the WiFi PHY layer, the bootloader to start code from external ROM and some bits of code to form a rudimentary scheduler. One of the reasons all this is in ROM is so in...

Re: ESP32 - External flash memory - Quad SPI access question

Okay, I don't really understand your 'finally' then - accessing the program SPI in quad mode has always been possible from what I know. Just make sure to enable it in make menuconfig: Serial flasher config -> Flash SPI mode.

Re: ESP32 task privilege change

FWIW, the hardware PID generator is entirely unused in the current esp-idf setups.

Re: Is it possible to create a wifi jammer with esp32?

It may or may not be possible, however using our products for destructive purposes is not something we as Espressif want to support. Please do not do this.

Re: Robust method to receive data from UART?

Well, as UART data is just a stream of bytes, there's no guarantee whatsoever that it appears as one chunk on the output side. If you effectively want to send packets over the UART, you'll have to packetize/de-packetize them yourself.

Re: [SOLVED] BLE and Wifi = out of memory ??

Well, the BT controller uses up some memory, so enabling ity may just tip you over the edge. Suggest you take a deep look at the memory usage of your app and see if you can save some bytes somewhere. Alternatively, see if you can change over to an ESP-Wrover or something, so you can use the 4MiB PSR...
