Description
With firmware 1.12 the SetupAndConnectNetwork function was initializing Ethernet with DHCP on a POE network just fine.
Since 1.14 this does no longer work and the function returns false every time although the network is correctly connected and the NetworkInformation class returns a valid IP.
With a static IP this works just fine, but not with HDCP.
I tested with a Pi-Hole DHCP server as well as with a Unifi UDM Pro Router
How to reproduce
- Flash the OLIMEX With the latest firmware:
nanoff --platform esp32 --target ESP32_OLIMEX_WROVER --serialport COM<yourPort> --update --masserase
- Run the following program:
public static void Main()
{
bool IsCommReady = false;
NetworkInterface[] allNetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
NetworkInterface[] array = allNetworkInterfaces;
foreach (NetworkInterface networkInterface in array)
{
if (networkInterface.NetworkInterfaceType == NetworkInterfaceType.Ethernet && networkInterface.IPv4Address[0] != '0')
{
var ip = networkInterface.IPv4Address;
Debug.WriteLine($"IP: {ip}");
IsCommReady = true;
}
}
if (IsCommReady)
Debug.WriteLine("Ethernet Connected");
using (CancellationTokenSource cs = new(60000))
{
Debug.WriteLine($"Trying Ethernet...");
IsCommReady = NetworkHelper.SetupAndConnectNetwork(cs.Token);
}
if (!IsCommReady)
Debug.WriteLine("SetupAndConnect Ethernet Failed");
}
- Debug or execute the program.
It will show "Ethernet Connected" and a valid IP, but once it hits SetupAndConnectNetwork it will stall for 60 seconds per cancel token and then returns with failed.
Expected behaviour
This works just fine with Firmware 1.12
