DHCP Discover Requests Constantly Sent

Question asked by Robert Stevens on Nov 9, 2018

We are using MQX 4.0.2 for DHCP and Static IP connections to communicate to a PC (and other devices). We've recently come across a situation where we see our device, while attempting to get an IP address, just start and stream requests like crazy.... 

 

All of the discover messages above are from the same device and our firewall is giving us the offer, but for some reason we are not accepting it. More strange is that we just send these messages, back to back, without any sort of wait time in between. 

 

Today, we have our state machine setup to call ipcfg_bind_dhcp() until it returns 0, then we periodically call the ipcfg_poll_dhcp() until that returns 0. 

 

Any help would be greatly appreciated!
