PPP over Serial test
Testing connection of PPP client (ESP) to PPP server (raspberry pi)
Pin Assignment
| ESP | rpi |
|---|---|
| GPIO25 | UART-RX |
| GPIO26 | UART-TX |
| GND | GND |
Test workflow
- Starts PPP server on a linux host
- Starts PPPoS client on ESP board
- Connects with both IPv4 and IPv6
- Test IPv6 connection
- Start server on ESP
- Have linux host to connect and exchange some data
- Test IPv4 connection
- Start server on linux host
- Connect with ESP to the server and exchange some data
- Pass/fail
Manual test
Server side
sudo pppd /dev/ttyAMA0 115200 CONFIG_TEST_APP_PPP_SERVER_IP:TEST_APP_PPP_CLIENT_IP modem local noauth debug nodetach dump nocrtscts
or with +ipv6 to support ipv6 assignment
IPv6 test
Connect to the ESP local link address and send data, e.g.
nc fe80::74d7:edc5:9907:5457 2222
IPv4 tst
Server side expects to run tcp server on port 2222
nc -l 2222
