Mbed-os: EthernetInterface MBED-OS 5.3 static IP

[andcor02]

Hi,

I am forwarding the issue from multiple users have problems setting static IP in MBED OS 5.

Problem:

• Users cannot set static IP

• Users have tried to use: virtual nsapi_error_t set_network(const char *ip_address, const char *netmask, const char *gateway); However the following errors are output

Example network-socket TCP Server
set IP status: 0
connect status: 0
IP address is: 192.168.1.100
MAC address is: 8a:42:7d:87:0c:b7
open error: -3004

Error -3004 is "not connected to a network"
However I can ping the module on it's assigned IP address and it responds to the ping so we know the network is indeed connected.

Needs the patch pointed out by YixiaoLi

It looks like the initialization of lwip for static ip addresses doesn't set a dns server. It does for ipv6, but it looks like the path for ipv4 relies on dns servers from dhcp. Working on a patch to fix this.

Hopefully #3526 resolves all these problems, let me know if there are still issues.

This issue still seems to exist. I have tried to use 5.3.3 and 5.3.5 and still have no success setting a static IP address. The original ticket is: https://github.com/ARMmbed/mbed-os/issues/3524

I believe this is still an issue.

@cldpinheiro what device and compiler did you test with? On a K64F (mentioned as the device used in the original issue) with GCC_ARM at the head of mbed-os (commit 78a1eddf61efa705ef1e99fc597dcaa5e737fb4c) I cannot reproduce the error. I get the following running the linked example:

Example network-socket TCP Server 
set IP status: 0                  
connect status: 0                 
IP address is: 192.168.1.100      
MAC address is: a6:43:49:7a:c2:c2 
server open                       
Bound                             
Listening
