Some issues (dns, wifi not disconnecting) with reliable ethernet connection with wifi fall back

Firmware Device OS
1

hello

we have a board with p2 and ethernet and are trying to get reliable ethernet connection with wifi as fall back. it sort of works but we see some strange things:

-1- attached to ethernet we get no dns address - Ethernet.dnsServerIP() = 0.0.0.0 - (attched to wifi and the same dhcp server we do get an dns address). it will not connect to the cloud unless the board was connected to the cloud before (e.g. attached to wifi) -- is this a bug?

-ad 1- if we do not get a dns server address: can we use Ethernet.setConfig() to set a DNS (e.g. 8.8.8.8)? how?

-2- when it has been attached to wifi and we turn of the access-point falling back to ethernet works (we use: WiFi.disconnect() and Ethernet.connect()). but even though it attaches to ethernet and connects to the cloud i see in the logging attempts to attach to wifi. turning the access point back on we get a situation where Ethernet.ready() and WiFi.ready() are both true even though we did a WiFi.disconnect()

thanks
frank

note: our ethernet is on alternate pins
note 2: device os 5.4.1

i used wireshark to checkout what goes on. in this case ethernet does connect (mac sharing internet):

  • the dns address is given to the p2 in the dhcp communication but p2 reports dns = 0.0.0.0
  • in this case p2 seems to have cached the particle cloud address
  • see a lot of "Malformed Packet"s

capture where it does not want to connect to the cloud (directly connected to my local network):

here is the logging (fails to connect to the cloud):

Ethernet. dnsServerIP() is not supported. It will always return 0.0.0.0 even if it gets a valid DNS server address by DHCP.

ah, ok

do you see any other issues why it might not connect? our ethernet/wifi is based on your lib

pretty much:

switch to ethernet:
WiFi.disconnect();
Ethernet.connect();
waitfor(Ethernet.ready)
Particle.connect();

switch to wifi:
Ethernet.disconnect();
WiFi.connect();
waitFor(WiFi.ready)
Particle.connect();

i am now just testing ethernet connectivity (no wifi credentials):

  • connected to my mac with a usb ethernet adaptor and internet sharing works well almost every time
  • directly connected to my local ethernet network does not work most of the time. even had it "freeze" the p2 (no led, no nothing). see below
  • when connected it is reliable / stays connected

how can we debug this?

any help is greatly appreciated
thanks
frank

the dhcp communication for both is almost identical, except for "next server ip address" which is 0.0.0.0 for the network that the p2 does not want to connect to:
