update both firmwares at the same time.

This would be good. Especially if I don't need to keep the firmware binary stored on the P4.

ESP32-P4 results at 360 MHz Integer Addition 319.520721 MOP/S CPI=1.001140 Integer Multiply 319.680328 MOP/S CPI=1.000406 Integer Division 319.680328 MOP/S CPI=1.000401 Integer Multiply-Add 319.744202 MOP/S CPI=1.000381 Float Addition 318.249634 MOP/S CPI=1.004953 Float Multiply 319.648376 MOP/S CPI...

One way to do it (might be the same as @thefury) is: Configure one of the I2S as slave then share the clock signal. The GPIO trick can be referred to from components/esp_driver_i2s/test_apps/i2s/main/test_i2s.c: i2s_test_io_config . After I2S finishes initializing GPIO, use esp_rom_gpio_connect_out...

I've been asked to determine the percentage of packet error rate on ESP32. (Bluetooth classic, main application is A2DP & SPP)

How do I go about doing this? I haven't found anything through my googling around on bing. There doesn't seem to be an API that provides the info.

Interesting. When I call esp_ble_gap_config_local_privacy(true); and set adv_params.own_addr_type to BLE_ADDR_TYPE_RPA_PUBLIC, the inquiry response gets the class of device right away. BLE has a different address, then, which I think is fine for my purposes. However, now the inquiry scan has two sep...

If all else fails, you can try to send custom advertisements. Although, from the issue I gather that you're using the libraries own SPP service which may override any custom advertisement... I did try turning off any manufacturer specific data packets from my Bluetooth LE advertisement/scan respons...

Has anyone else observed a delayed Class of Device / UUID list response? What could cause it? Might be that CoD and other data (UUID list) are not (automatically) included in your advertisements. I don't seem to have much control over it. I just call esp_bt_gap_set_cod before becoming discoverable ...

I am working on a custom board for a customer whose application requires a specific Class of Device because they are depending on BlueZ's "icon" field (found to be determined exclusively by the CoD). My ESP32 system seems to respond to it very slowly, in that the Class of Device and UUIDs list does ...

A true successor to the ESP32, in my humble 2.5 cents (inflation!), from the perspective of an audio system, after having gone through a couple of prototypes with ESP32 and/or ESP32-S3: Keep the APLL, it gives a cleaner MCLK than ESP32-S3 does. This helps with signal-to-noise ratio on DACs that don'...

We have started to evaluate ESP Insights as a solution for remote debugging and logging, maybe OTA updates (but I currently have a solution for OTA updates using our GitLab CI/CD). I have tried to invite a teammate to my ESP Insights dashboard; the email did not arrive and he does not see the incomi...
