Nachiket Kukade 6fd6a8b40b esp_wifi: Always connect Station in PMF mode if possible 
While using esp_wifi_set_config, flag pmf_capable defaults to 0.
Users may not bother to enable it, which prevents connection to a
WPA3 AP. Or the AP may reset into WPA3 mode failing the re-connection.
To ensure better security, deprecate the pmf_capable flag and set it to
true internally.

Supported Targets ESP32

BLE peripheral with ICMP Echo-Reply.

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example aims to run ping network utility along with BLE GATT server simultaneously using NimBLE host stack. It is a combination of 2 examples in IDF: bluetooth/nimble/bleprph and protocols/icmp_echo. See the README.md files of these examples to know more about them.

BLE peripheral

This example creates GATT server and then starts advertising, waiting to be connected to a GATT client.

It uses ESP32's Bluetooth controller and NimBLE stack based BLE host.

ICMP Echo-Reply

Ping is a useful network utility used to test if a remote host is reachable on the IP network. It measures the round-trip time for messages sent from the source host to a destination target that are echoed back to the source.

Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply.

Notes: Currently this example only supports IPv4.

How to use example

Configure the project

idf.py menuconfig

  • Enter SSID and password of known WiFi AP with connectivity to internet.

  • Enter desired ping IP Address. Default is set to 93.184.216.34 ( This is the IP address of https://example.com ).

  • Enter other related parameters like count of ping and maximum numbers of retry.

Testing

To test this demo, any BLE scanner app and a WiFi access point with internet connectivity can be used.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
