Hello,
Sometimes this can take a bit of trial and error to figure out what isn't working.  Please try the following:
1) Open the AirTurn Manager App on your tablet, and see if a firmware update is available for the pedal. If so, install it.
2) If the pedal is currently paired in the bluetooth settings, unpair it and forget the pairing.
3) Put the pedal in mode 1, and hold the power button for 9 seconds (it should blink three times and then you can release).
4) Turn the pedal back on, open MobileSheets and go to Settings->Touch & Pedal Settings->AirTurn Direct Mode. Also make sure you have granted MobileSheets bluetooth access and/or access to nearby devices if you haven't already done so. This is critical for connecting the pedal (you should also go to the main tablet settings->Apps->MobileSheets->Permissions and verify that you've granted the permission and it hasn't been turned off, as that can happen after a while).
5) Turn on the AirTurn support toggle, connect the pedal, then go to Settings->Touch & Pedal Settings->Pedal Actions. Tap the keys field for pedal 1, then tap Clear. Now press the pedal switch. If a key shows up, you are in good shape. Set the action for the pedal and repeat with the keys field for pedal 2.
6) If this doesn't work, close MobileSheets, put the pedal in mode 3, hold the power for 9 seconds again, go to the tablet bluetooth settings, pair the pedal, then go to Settings->Touch & Pedal Settings->Pedal Actions, and try to set the pedal keys again.
Hopefully that will get the pedal working again, either in mode 1 or mode 3. Let me know if you run into issues with this.

Thank you very much Mike for your advice and the procedure. I followed your advice (I started again twice)
unfortunately, I did not succeed in mode 1 or mode 3 in making the pedal work with MobilleSheets. And more annoying, like Friday cannot connect the pedal and yet it appears in bluetooth devices. But it is mentioned " connection to the device (serial number) is impossible. when I try to connect with Air Turn Manager it says :
Connection failed – connection to BT500S-2 V3.0.9 10 E2 failed :io.nrgtech.rxandroid.exceptions.BleDisconnectedException : Disconnected from MAC='C7:6F:4C:F3:21:XX' wirh status 0 (GATT_SUCCESS) ???
I have to go on the road for concerts. I can write to you again on Monday when I return. Thank you again for your help and patience.

That's definitely not a good sign. If the AirTurn Manager app can't connect, you may need to contact AirTurn about that error to see if they have any recommendations. You may have to return the pedal... I'm assuming you tried holding the power for 9 seconds to reset the pedal before trying to connect to the AirTurn Manager app, but if not, give that a try.

Mike,
thank you for your reply. When I got home yesterday I contacted AirTurn. Here is their response : "Just reset the pedal, as that resets the Bluetooth connections. To do that turn the pedal on. It just needs to be sitting there blinking. Then press, and hold down the Power button for 20 seconds to reset the pedal. Turn the pedal back on after the reset if needed. Try to pair. You can't pair in Mode 1. I had suggested Mode 2, or Mode 3."
 
I think I'm going crazy with this problem... I followed their advice. Now the pedal is well recognized. I used mode 3. I did a test by going to a website. I can scroll through pages on this site. Only…
In MobileSheets I go to Settings->Touch & Pedal Settings- (I have not activated “Air Turn Support”) On "Pedal Actions " I open PEDALE 1 and I press the right button of the pedal. I see the key : PAGE-DOWN or PAGE_DOWN, PAGE_UP if I press on the left button. by clicking on "action" and clicking on the small down arrow on the right of the screen, I bring up the "select pedal action" screen. But it is checked "go to next page". So I don't know what I need to do to be able to rotate my scores. Help ! Please. Thanks again.
