ESP32-S3 in WPA2-Enterprise networks with 802.11R (Fast BSS Transition)

Hi, reading the ESP32-S3 documentation about the 802.11R (Fast BSS Transition), I discovered that "ESP32-S3 station supports FT for WPA2-PSK networks". Is there any plan for the implementation of the 802.11R also for 802.11X (WPA Enterprise) networks? The benefits of using 802.11R in 802.11X network...

Re: mqtt_client keepalive

Everything is good... ok, the mqtt client is working, but I still do not understand the choice of halving the keepalive interval... why not choosing keepalive - 1 or keepalive / 3... My customers make me notice this behaviour, they setup the device with a keepalive value and then they discover that ...

Re: mqtt_client keepalive

In my opinion this is completely misleading. The keepalive interval is expressed in seconds, so if I set to 30, I expect that the mqtt client will ping the Broker every 30s, not every 15s. Moreover, mqtt Brokers do not timeout the connection if the ping is not received exactly at the elapse of the k...

mqtt_client keepalive

Hi, I'm using the ESP mqtt_client library with ESP-IDF v4.4.4 and v5.0.1. In both SDKs, the real mqtt_client keepalive value used seems to be the half of the one set in the client configuration. I have checked this looking at the mosquitto logs and looking for the PING_RES / PING_REQ from my client....

Re: ESP32S3 + W5500 - Basic Ethernet Example detects stack overflow

The problem seems to be related to the debug log verbosity.
Decreasing log level to "Info", solves the problem.

ESP32S3 + W5500 - Basic Ethernet Example detects stack overflow

Hi, I have connected as ESP32S3-DevKitC board with a Wiz850io board to test SPI ethernet on ESP32S3 device. I have configured the Basic Ethernet Example and let it run on the board. The example runs fine, it is able to initialize the W5500 and connect to the Ethernet, but after a while (10-15secs.) ...

Re: ESP32-S3 as BLE HCI-UART Host only

I've already obtained some successful results porting the default ESP-IDF implementation (that uses the internal VHCI interface) to use a real HCI-UART interface (now I'm able to send HCI commands / receive HCI events to an external nRF52 that runs Zephyr). But it required to understand how Nimble s...

ESP32-S3 as BLE HCI-UART Host only

Hi,
does anyone know if using ESP-IDF, is possible to configure the ESP32-S3 as BLE HCI Host only that uses HCI-UART as transport layer to communicate with an external BLE HCI-UART Controller?

ESP32S3 as BLE HCI-UART Host with Nordic nRF52 BLE HCI-UART Controller

Hi, I would like to use the ESP32S3 as a BLE HCI-UART Host connected through UART to a Nordic nRF52 BLE HCI-UART Controller. In this hardware setup, ESP and Nordic are connected through UART and on the Nordic MCU will run an HCI-UART Controller firmware. I would like to use the ESP to send HCI comma...

Re: Wifi scan while connected to an AP

I understand which was my problem. Reading the wifi documentation I have found this: the found APs are stored in WiFi driver dynamic allocated memory and they will be freed in esp_wifi_scan_get_ap_records, so generally, call esp_wifi_scan_get_ap_records to cause the memory to be freed once the scan ...
