Hello,
I am working in our company with CAT S40. We have 10 of this devices and all show the same behaviour:
1. I turn on the NFC option to read NFC tags.
2. I Start an app which can read NFC tags.
3. I am reading with the app several tags
4. I make a power off of the CAT S40 and turn it then on again (or make a restart)
5. I am starting again the NFC app and I can not read any NFC tags anymore
6. I go to the setting and checking the NFC settings. The NFC setting is set to ON.
7. I turn OFF the NFC settings and then turn them ON again
8. Now I switch back to the NFC reading app and now it is possible to read tags
Has anybody experience with this behaviour and how can I solve this issue?

Overview: We have developed an app that allows customers check in using an NFC enabled card with a stationary Nexus S. The app sit ready to read a card, when a card is tapped, the app reads the unique ID for the NFC card.
Problem: The challenge we have run into, is that the Nexus S locks up after scanning 50 to 100 tags. The app continues to function, and so does android, however neither our app, or the native app within android will read a tag. It is as though the scanner has been disabled. I have tested it using 4 different Nexus S devices running Android 2.3.6.
Debugging: The only solution I have been able to find is to either: - power the nexus s off and then power it back on - disable NFC and then re-enable it through Setting --> Wireless & network settings --> NFC
If either of those are done, the scanner works again and app continues to work as normal until it locks up again after 70 or so scans.
Any idea how to fix this bug, or work around the issue?
Update: it appears as though this is not just with our app, testing the "Tags" native app that comes with the Nexus S also has this issue.
Do you see any output in logcat relevant to NFC?
Hi, i have a question related to the NFC tags.
-I recently bought a second set of the sony nfc tags (the set with the four colours) but unfortunately i realized that even if it is a different set (physically) the red, blue, etc tag is not recognized as different but as the same tag. Pex both reds do the same actions both blues the same etc. How can i assign to them different actions?
- A second question is that as i understand each tag has 2 states a state that enables certain actions and a state that disables them (???)
As for now i can only activate the actions related to the specific smart tag and nothing more. So when i will activate the actions of the tag how do i return to my previus sate??
Use NFC Task Launcher instead. It's a much more comprehensive NFC automation application than Xperia Smart tags, and addresses both of your issues.

I use my tags around the house /car ,I have found that the car tag turns on the Bluetooth, but seams to turn it off shortly after... The phone is fine as Bluetooth works fine with that, just the tags don't fully work??

I'm new to using Tasker but figured out how to make my GPS turn on high accuracy mode and bluetooth on and off when it is plugged in to the car.
All I did was create a new profile > State > power > changed source to AC, then using secure settings plugin had it enable GPS, then changed state to inverted to have it turn off ( I could of used exit state which I just figured out). It works, changes to high accuracy when it's plugged in then battery saving mode when it's not.
Thing is, I'd like a 5 minute delay before it turns off and I can't figure out how to do it. I did find a profile on the Tasker Wiki that turns BlueTooth off with a 5 minute delay that works fine, I figured I could learn from it and do the same with the GPS, but nope.
Can anyone help me figure this out? Thanks for any help
I finally decided that I was missing out by not having Tasker automate my life for me, so bought it as well as the full version of Secure Settings.
I've managed a couple of simple Profiles, but I'm having trouble with other stuff I want to do - most likely because I just don't understand.
A. Aim: When Maps is launched, turn on "WiFi" and "Location Mode High Accuracy"
Profile: Near Work
State: Cell Near (work)
Tasks: (1) WiFi On (2) Secure Settings, Location Mode/High Accuracy
This almost works - opening Maps carries out the expected tasks, and when I exit maps WiFi turns off (desired behaviour). However, Location does not switch off again, it stays on switched on, and I don't understand why.
I'd like Location to switch off again when I exit Maps.
B. Aim: Switch on WiFi and Location Mode/Battery Saving and Location Reporting and Location History once an hour, for one minute, and allow (force?) Google to poll my location for a short period so that if I ever lose my phone and it is switched off, there will be a trail of sorts (without having to leave all these services switched on all the time,which canes my battery).
Profile: Manage Location Services
State: Time - I don't know how I can make the profile active for one minute, every hour
Tasks: (1) WiFi On
Then I get lost - I can't see how to enable Location Reporting which is in Location Services in my phone settings. Also I don't know if doing that would immediately prompt the phone to contact Google and report its location (I assume it would).
C: Aim: Between 10pm-9am, if at home, then silence phone and switch off notification light
State: Cell near (home)
This is as far as I've got. I don't understand how to use time as a defining factor. Nor do I know how to switch off the notification light.
If anyone could help then I'd be very grateful!
Also, after reading a lot of Tasker walkthroughs/userguides (and not understanding a lot of them) I am none the wiser as to how to set up an 'exit task'?
There are a lot of issues regarding Secure Settings, I don't recommend it. The only way to turn on/off gps (and the way I'd do it personally) is use root shell to navigate through the settings or better yet set Status Bar-Open and using a Shell-"input tap x y" Use Root: Yes to tap on the GPS quick setting widget.
To add an exit task simply long press on the action part of your profile (on the main screen) and the options will appear. You can also add additional State, Time or Action matchings to your one profile, by long-pressing on the left part!
<<< Please say thanks if I was of help.

Hello,
Have any of you had a problem of auto disconnection with the application? I have already restored the factory settings several times and the problem still occurs maybe one of you had such a problem and could advise me how to deal with it, I don't get any notifications, which starts to irritate me
Regards
what device (model and ROM version) and what phone? Without any info about your setup it's very hard to try to help...
Anyway, the most common causes to connection issues are other app that may conflict with Amazfit app or kill it while in the background (check your phone settings) and Bluetooth/WiFi conflict. To test the later, disable all WiFi, put phone in Airplane mode then turn only Bluetooth on and see if connection gets better.
I have Stratos A1619 with PolishROM my phone is Huawei Mate 10 lite, but on any kind of ROM that problem occurs
Put your phone in Airplane mode and turn on only Bluetooth, make sure Amazfit app is open and running, confirm that watch is connected then move watch away from the phone. How far can you go without disconnecting? If it disconnects after just 30-50cm then most probably it's a hardware issue. But I'd recommend that you go entirely stock to test these things, it's hard to pinpoint anything using modified ROM.
Heey, you have options in that place where you can uninstall app, battery saving mode or optimization - sth like that. I have stratos and note9 and i have the same problem. Watch seems like have connection (top options at top left symbol phone with tick that means - connected to phone). But phone is saying disconnected. What helps - turn in airplane mode in watch, wait few seconds and turn airplane mode off.
But as i was saying - check battery optimization options and turn that function off in phone. If you are from Poland then write to me PM - i try to explain this in out native language
