Bryton Rider 450: Tracklogs and Following Routes

I’ve just started doing some audaxes and whilst GPX routes are often supplied, you can often start at any point. This made me wonder whether you could follow a route on the Bryton Rider 450 from any point along it. The good news is that - yes - you can, however that comes with one major problem. When you get to the end of the route the map screen goes blank and tells you you’ve “Arrived”. What I want it to do is just carry on from the beginning again which the Rider 450 won’t do. This is perhaps unfair behaviour to expect of it and maybe an “edge” case, which means the route would have to be digitised again for your starting point.

The tracklog does carry on recording and this goes to show that the tracklog and map routing are completely separate activities running in parallel on the device. Precedence is giving to tracking is this is highly time dependent. It explains why the maps take time to refresh and the longer the routes get, the longer they take to load. This can at times can give the impression that the unit has frozen, when in fact it’s reading the whole route back in to memory, take the current GPS coordinate, load the correct map tile, then plot the breadcrumb trail over the top.

It also further highlights that the map screen doesn’t refresh until new information is ready to display, again behaviour that might suggest it’s frozen (and indeed it may lockout other actions until this is complete). Crucial to this series of events is being able to get a GPS coordinate: if it can’t do that, the map won’t update. This means that if your system can’t get satellite lock (in a tunnel, under trees etc) then the maps remain frozen until a coordinate is supplied. The tracklog however should carry on recording (doing whatever the recording algorithm dictates for a lack of current coordinate). The key then is patience: just carry on cycling. This has happened to me on a number of occasions making me reboot the system when it probably wasn’t necessary.

Of course if you genuinely do have a frozen Rider 450 then it will need rebooting! Remember that means pressing and holding the four side buttons for a few seconds, then releasing them. Once rebooted it then needs to go through the whole process of satellite lock and getting a first coordinate this can take minutes the first time after a reboot.

Forcing a Public WiFi Login Page to Load

WiFi (and internet access) is so endemic that we often think of it as an essential utility rather than a useful add-on and it’s got to such a point that just about every restaurant offers some kind of service. Whilst inherently less secure that private WiFi, they can be great to jump on to in order to download some Netflix shows or update some apps. The default action once you’ve connected to a service is to load a default login page in order register and verify your credentials. However problems arise when the default page doesn’t load. This has happened to me for three reasons:

  • Puffin Browser: it’s a great mobile browser that is fast because it saves data. It does this by pre-loading the page at a server then sending you compressed versions. By default, this means that the Puffin server is trying to access the login page, but obviously can’t because it’s not on the network! The solution is to use a “normal” browser such as Chrome, Brave, or Firefox.

  • Alternate DNS: if you’ve changed your DNS to try to speed things up and have a little more security then this might be the cause of your problem. The login page will be unique to the WiFi network, so asking OpenDNS or GoogleDNS to do a DNS lookup will fail. The solution is to remove this setting and then use the DNS provided by the WiFi, which will allow your browser to load the login page.

  • Browser Cache: if you’ve visited a website before then it’s possible the DNS lookup will have been cached. You try to go to the site again, it bypasses the login page and then can’t load the remote site. The solution is to avoid using cached data and then force a new page to load. The simplest solution to the first part is to start a new incognito page which is sand-boxed and can’t access an cache information. Loading a new page ideally requires an http connection (not https as this won’t allow redirection to a login page for security reasons). These are much rarer than you might expect, however ICAAN’s example.com is a great option.

The third one crops up more often than you might expect, so it’s good to have this fix in the bag!
