It seems AMB82 has H264/H265 support, so you can make it possible for 1080P/30FPS with much lower bitrates. UART is much simpler that SPI, and ESP32S3 UART supports up to 5Mbps. Also you may limit the bitrates on AMB82 side, and I beleive that AMB82 has such kind of API. So the conclusion is that: 1...

This is the A-MPDU related feature introduced into Wi-Fi since Wi-Fi4. W (223029) wifi:[ADDBA]rx delba, code:37, delete tid:0 Means in the Rx direction, Block Ack Agreement is deleted because of reason(37). Look up the IEEE802.11 spec, you can find that 37 means "Requesting STA is no longer using th...

I think you may totally disable PSRAM. If that helps, then you may use octal PSRAM with 80MHz or 120MHz.

You need fixed point decoder which is for MCU without hardware float.

Maybe you should share your ethernet PI configuration, like this I used for my ESP32-S3 + W5500 Espressif IoT Development Framework Configuration [*] SPI Ethernet (1) Number of SPI Ethernet modules to use at a time Ethernet SPI (W5500 Module) ---> (1) SPI Host Number (12) SPI SCLK GPIO number (11) S...

I think memset break the status of the dns table entry. Maybe we should borrow the internal-built mechanism, such as TTL. We may set the TTL of each entry to a small value such as 5, so the tmr of DNS can invaid it in advance. Realted code: 1187 case DNS_STATE_DONE: 1188 /* if the time to live is nu...

Glad this will help, and according to your description, I think you may put the gatekeeper code to enable/disable BLE passage just before the final input function. +---------+ | BLE | +---------+ | v +----------------+ | Gatekeeper | +----------------+ | v +-----------------+ | Service Handler | +--...

I am afraid that you may still choose to use some special attribute for second-step auth. Here is my sugguestion: For enhancing the security of your BLE setup, you can implement a mechanism using a special attribute that must be written with a correct session key or similar password. This attribute ...

You need to call dns cache clear within LWIP task context. #include "lwip/tcpip.h" #include "lwip/dns.h" #include "stdio.h" // Data structure for passing to tcpip_api_call struct dns_clear_cache_call_data { // No parameters needed }; // Function to clear DNS cache void dns_clear_cache(void) { extern...
