SApp Not Working Correctly

So i purchased the Arc Pro power base and wireless controllers and all worked well when i first installed and tested after doing the power base mod. I then removed all my wired controllers and associated wiring. And all seemed to work well initially but now nothing works as it should. For example, when i turn on the base and controller, and place a connected car on the track, i should be able to operate the car but it doesn't move. Throttle action shows up on screen. If i proceed to do a pace car race, the pace car speed sets correctly. I place a connected and set up car on the track and start the pace car race. The pace  car takes of as it should but it counts three laps every lap. The connected car takes off with throttle actuation but slowly. Then goes on auto pilot. It doesn't respond to the controller at all and laps completed do not register at all. I've tried restarting the power base. I've deleted the app and downloaded again. I can switch to another connected and set up car and it does the same thing. My grandson was over a few days ago and we tried a two car race. One car operated as it should but was counting triple laps and the other car would only go slowly and didn't count laps. I've tried it with Asus tablet, Samsung Galaxy S7 phone and BlackBerry phone. The devices all work about the same. We're working of a Verizon 5G wireless connection. The router is only about 10 feet from the power base with a direct line of site between the two. Frustrating as hell. I guess that's why we call it a hobby, eh?

First , you have not done the mod.

You have connected the arc app.

 

Will the cars race without the app (tablet off) ?

Hi Lonborghini - welcome to the forum and a Happy New Year to you!

 

As gorp said, check if everything works okay out of the app first. I suspect that you need to check and double check that the cars are connected to the colour you think they are. The IDs are different from previous digital powerbases to ARC Pro, so you will need to re-connect them to ARC Pro. Also make sure the controllers are connected. Otherwise swapping over the powerbases (what you describe as the 'power base mod') should work fine.

 

The biggest learning curve with ARC Pro is what I call 'the rule of the three colours'. The colours on the powerbase, controller and of the driver/car in the app must all match. The default colours are red and green, so I always start with those and then add blue, yellow, orange & white in that order. Each controller should be connected to a colour on the powerbase & you also connect each car to a specific colour on the powerbase - these two processes are explained in the Quick Start Guide. Connect a car to red and you control it with the red controller - whether the app is on or off.

 

The third colour connection is to match the car ID (the colour on the powerbase the car is connected to) with the background colour of the driver tile in the race set-up menu of the app. This is the sliver of colour to the top and left of the tile. Set-up a car/driver on the red tile (default = Driver 1) and the powerbase lap sensors will search for the car connected to red on the powerbase and display data for it in the app. If you set up the car on another colour in the app, the red controller will still control the car connected to red, but no data will be recorded. It will seem as if the app isn't counting laps - however, it hasn't been set up to 'see' the car. Remember, all three colours must match.

 

I also see that none of you android devices are on the campatible device guide. You could browse the thread to see if there is anything discussed about the Asus or the S7. The thread is here: https://www.scalextric.com/uk-en/forum/arc-app-device-compatibility/

 

I hope that helps.

Gorp, yes i did the power base mod of reversing the two wires because i am not running isolated lanes and am only interested in digital operation. Very easy to do. After the mod and inserting the power base into my layout I did connect all six wireless controllers and connected to six cars. I then did several laps with each car to verify operation and make sure all lane change sections operated with all six cars. No problem. I did do a few pacer races with no problem. Then things began to deteriorate. Some of those pacer races were definitely run with the pacer and the red car. Right now i'm not positive the cars will run with the app off. I did do a two car race with my grandson and one car went slowly and the other recorded triple laps. When i return home in a couple of weeks i'll do some further testing and i'll get back to you. Thank you for your help.

Hi lonborghini. Thanks for clarifying your mod comment. Although it is worth checking out your use of the app and the basic connection procedures, my advise is to contact whoever published the mod you have used. I presume that is either Riko Rocket or Dr_C who have both posted their mods on Slot Forum: https://www.slotforum.com/forums/index.php?s=5aa07b24cd39e6dfa63f5b4c690f48c7&showforum=370

 

If you post pictures of you mod over on Slot Forum, plus the issues you are experiencing, they should be able to check you work. It could be the mod is fine, but as you say the powerbase only had problems after you did the mod, that seems the obvious place to start.

Could it be that without the app the powerbase thinks it is in analog mode ad because of the mod it shorts out?

Woodcote, actually i did the mod, which is just unsoldering two wires, switching positions, and resodering, before i ever used the powerbase at all. Afterwards i connected wireless controllers and cars. In subsequent testing everything worked flawlessly, until it didn't. Andy, i presume that a short would trigger overload functoin and base would shut down unitl problem resolved. We'll figure this out when i get back home, maybe. Thanks.

Hi lonborghini. I guess we have given you a lot to look at when you get back to testing! Do let us know how you get on.

 

Having read through this thread again, I would urge you to get your hands on a smart device from the official ARC compatibility list: https://www.scalextric.com/uk-en/forum/arc-app-device-compatibility/ - otherwise whatever else you do, you might just be chasing a device compatibility issue, which would be very time consuming and frustrating. If you can borrow a device from the list, we can help trouble-shoot - first without the app, then with the basic race and lap-timing features of the app and then adding in advanced features like the pace car and incidents etc. At this point in time, I can't tell if there is a hardware issue, software issue, compatibility problems or damage from the mod - or a combination of some or all of those.

no Andy, no

 

the mod is Riko's, pinned and locked at the top part of first page of slotforum arc pro forum

 

first step remains : will the cars race without the app ? (without the app)

 

So i'm home for the weekend had time to experiment some more. Yes, all six cars work without the app. No problem. The lane change function works with all six cars at any of the lane changers. My grandaughter was over and we were able to operate two cars without the app, no problem. I expect that with six drivers we could operate six cars without the app. No problem. She downloaded the Scalextric app on her iphone 7 plus and we had the same results as with my Samsung 7. We ran a two car race but one car that previously operated correctly with out the app, would only go slowly with power set at 75% or 100%. The laps were registering correctly. As before if we ran a pacer race, the pacer's speed would be as set but, the manually operated car would top out at about 50% power even though that car was set up for 100% power and did not register laps but the pacer car would register three laps for every lap. That is, the pacer car would register a lap at the power base, another about 1/3 of the way around the track and another at about 2/3 of the way around the track. Not much new here.
