[lwip-users] ppp-new threading question

I feel almost embarrassed asking this but I haven't completely figured it out yet. In ppp-new, are packets sent to sio_write() from tcpip thread, or from the RX process thread? Or both? I just ask because sio_write() may block for some time (at least in my basic implementation) and I'm

[lwip-users] DHCP callback was removed - Correct way to obtain new address?

Hi all, I am just porting my application from version 1.3.2 to the latest 1.4.2. and I was wondering why my application does not get called back from the stack when the DHCP As I found out the callback was removed. My application has to know the address for displaying purposes, so do I have

Re: [lwip-users] DHCP callback was removed - Correct way to obtain new address?

Chris, I am using the TCP RAW. After starting DHCP I wait for the IP by using: While(main_netif.dchp-state != DHCP_BOUND). After the state changes to DHCP_BOUND the ip is in the pcb (main_netif.ip_addr). You can periodically check to see if the ip changes. I also include in the while statement

Re: [lwip-users] DHCP callback was removed - Correct way to obtain new address?

When I did it, I basically polled for netif.dhcp-state == DHCP_BOUND and read ipaddr = netif.ip_addr; netmask = netif.netmask; gw = netif.gw; but now I realize the dhcp code calls netif_set_up() when it reaches that state, which also calls NETIF_STATUS_CALLBACK if

Re: [lwip-users] ppp-new threading question

Ok, that's what I thought. I will have to re-implement sio_write(). What I'm concerned also is, sio_write() is meant to block until all data is pushed out. This can be more than a second in a slow 9600bps connection (still used sometimes!!!). Will PPP try to do something during this time like

Hi, ST micro has an example on how to use it. Check their latest examples for STM32F4 Hope that helped, Noam. -Original Message- From: lwip-users-bounces+noam=silrd@nongnu.org on behalf of Sergio R. Caprile Sent: Fri 8/29/2014 9:02 PM To: lwip-users@nongnu.org Subject: Re:
