apologies in advance if this topic's been addressed elsewhere, I searched but no joy
has anyone setup their BCS-462 using peer-to-peer/ad-hoc wifi? I don't need internet connectivity nor *distant* remote control (I'm always in the garage when brewing) just a reliable, lag-free interface. if so, is it straightforward)? any tricks involved? I don't want to direct ethernet connect the BCS to a PC - too many hazards
I'm obviously a network neophyte and would appreciate some guidance. or even a response of "I've done that..." would be great, then I'll know it can be done & will go figure it out
Thanks!
reducing wifi latency. any ideas?
Re: reducing wifi latency. any ideas?
I connect my BCS using a mini WiFi repeater bridge. It's powered by USB. Connects to the BCS using a short ethernet cable. The BCS connects just fine on power up. It was a bit of a pain to get the cheap Vonets unit I purchased configured but it has been great once I got it working.
Re: reducing wifi latency. any ideas?
jward - thanks for the positive feedback. do you peer-to-peer directly to the vonet bridge, or is the data path from the bridge connected to an infrastructure router?
Re: reducing wifi latency. any ideas?
The bridge connects the BCS to the single router that everything else connects too.

If you are in Range and do not need the Internet, just any router will do. I have mine connected to a wired wifi repeater connected to my main router (internet). I could have as easily just hooked up a router, plugged the BCS to the router, and connected to the router with my windows pc normally. Sometimes when I travel, I take an old router and my BCS to play with it. You do not need the internet for the most part.

oakbarn - THANKS!

Solved the peer-to-peer connection (used an old WiFi router) however the latency is still the same, typically 4-sec. guess that's just how it is

4 second latency? You have a networking problem somewhere.
When running my app that talks to the BCS, I update status nearly 3 times per second. Usually 300-400 ms update time.

Re: reducing wifi latency. any ideas?
entirely possible
I'm using an [older] Netgear WGT 624 v2 802.11b/g 108 Mbps wifi router, setup in auto 108mpbs mode, to which the BCS-462 is connected via ethernet
The BCS is set on factory DHCP mode. I can connect peer-to-peer & get the BCS main screen, etc from several clients including an I-Pad, a dell notebook (XPS M140) and a Lenova Tab 4-10
also, my "latency" measure is based on how frequently the Data Log updates. it seems to take 4-5 sec to refresh the temperatures (which are set to update at 1-Hz) and the screen refresh rate is device independent (I shot a 30-sec video of the screen but the video file is just too big (60+MB) to email)
your latency seems to be 10x less than mine, any ideas on improving this would be worth some good homebrew

Re: reducing wifi latency. any ideas?
Well, now we're talking apples to oranges. The datalog shouldn't be used to measure latency. It's designed to only update periodically. In most cases, you don't want to use 1 second intervals on it. If you're tracking a temperature over time, you'd want to use something of at least 1 minute or more.
My fast polling is done using the BCS API which is the same thing the web interface uses to poll data. Standard web poll & UI update is what should never be at a 4-5 second refresh. Usually 1 or maybe 2 seconds.
If you start a process on your main page and you have a timer running, do you see the screen update in near real-time showing the running clock? If so, then you have no latency issue. If you see the clock jumping in several second increments, then you may have a latency issue.
