David Cermak b3749e38f9 ppp-test: check if ppp interface is active and IP address correct before starting the test
Addressing stability of pppos test:
* listing active network interfaces for presence of "ppp0" interface
* fixed IPv6 address regex to prevent ttfw accept partial address only
(less than 8 octets)
* workaround crash after exiting app_main()

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
