Turning off CPU1 during runtime
Hello, it is not very frequently that my device needs both CPU cores to be running at the same time. In order to save energy, I would like to be able to turn the CPU1 on and off during my device runtime. I checked the sleep modes documentation for esp-idf v5.0.1 but I did not find a solution to my p...

ESP-BLE-MESH
Hi, I am currently making a BLE mesh of around 30 ESP32-S3 devices. Since ESP32-S3 has Bluetooth 5 capabilities, I wanted to know what is the highest acheivable throughput (kBps) for a maximum of 5 hops. How can I get this information? Do I need to change any specific configuration in menuconfig to ...

Re: Multiple PSRAM into memory mapping
But in the ESP32R8(V) example, there is only one external device. Or is a CS required for the SiP RAM too?

Multiple PSRAM into memory mapping
Hello all,
I would like to know if it is possible to use multiple sources of PSRAM to build more malloc-capable memory.
This could be, for example:
- An ESP32-S3R8 and an external ESP32-PSRAM64H tied to the SPI0/1 bus
- Two ESP32-PSRAM64H in parallel, tied to the SPI0/1 bus

Provisioning manager - Event when smartphone connects
Hello all, Is there a way to be notified as soon as one smartphone starts the provisioning routine, i.e. as soon as the BLE connection is established? From the example, I see these: WIFI_PROV_START, WIFI_PROV_CRED_RECV, WIFI_PROV_CRED_FAIL, WIFI_PROV_CRED_SUCCESS, WIFI_PROV_END But none of those see...

MQTT long messages guarantees
Hello all, I am receiving a long message (~550kb) through MQTT, so I get a great amount of message pieces along ~20s. I get all these messages from the MQTT_EVENT_DATA event type. Starting from the second piece of the message, there is no mqtt topic in the event object. So I was wondering: is it gua...

Re: WiFi + Provision working simultaneously
Hello again, I wanted to perform a similar procedure with the ESP32: I want the ESP32 to be open to new provisionings while it is trying to connect, to allow the user to change networks if the current is unstable. I tried to use those changes mentioned above, but I keep getting the errors: GAP proce...

Re: WiFi + Provision working simultaneously
Thank you, worked perfectly.
I did not use the second change so I could decouple the connection action from the provision action, so I called the connect function elsewhere.

WiFi + Provision working simultaneously
Hello all, I'd like my ESP32 to be open to new network configurations while connected to the internet. My situation is that the ESP32 should sometimes switch from one WiFi network to another through user input. Currently, I can set the ESP32 to connect to the first network through the WiFi Provision...
