ESP32 acts as a BLE Peripheral and simultaneously performs WiFi ping to configured IP address.

| ----------------- | ----- |
|
||||
|
||||
# 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.
