I created a one page cheat sheet with bar codes included based on all the previous information in this post.

Thanks for the correction..I actually did update it with the current DAT file...(I installed the CAB file to support the RS507 on the WT4070) but I am still having trouble "reconnecting" after I reboot the RS 507...If I reboot the ET1 and the RS507 it automatically recovers... When it gets into the failure mode I can check the status on the ET1...if I tap the device showing  Paired but not connected I get a message "Please press any key of your bluetooth keyboard to reconnect to the tablet"  the only thing I can do is scan a barcode...but that does not make the RS507 connect any ideas???

The RS507 retains the link to the last device it was connected. Did you press the RESTORE key on the RS507 to reconnect?

I now am able to change the battery and re-establish the BT connection between the ET1 and the RS507...The full solution 1) upgrade the scanner  PAAACS00-005-R00D0.DAT 2) Reset the RS507 to factory defaults 3) Configure RS507 for HID 4) On the ET1 enable the BT interface 5) On the ET1 discover the available devices 6) Pair the RS507 with the ET1  (I had to do this 2x to be successful) Following a battery change 1) Insert the battery and wait for the red lamp on the back and 3 chirps 2) Hold the restore button on the right side of the scanner for 10 seconds 3) Wait while the scan raster lights up followed by a beep 4) Go ahead and scan
Below is a summary of the available boot processes..these might be helpful during the pairing process Cold Boot

Cold Boot restores the RS507 operation by resetting its software. To perform a cold boot, remove and re-insert the

battery onto the RS507.

Clean Boot

Clean Boot restores the RS507 to its factory default configuration.

To perform Clean Boot:

1.
 
Remove the battery from the RS507.
 

2.
 
Press and hold the Restore Key.
 

3.
 
Insert the Battery onto the RS507.
 

4.
 
Keep holding the Restore Key pressed for about five seconds until a chirp is heard and the Scan LEDs flash
 
green. The RS507 is now in its factory default configuration.

Warm Boot

Warm boot restores the RS507 operation by resetting its software but retains the RAM content. Warm boot is used

when a log file has to be retrieved from the RS507 during application debugging.

To perform warm boot, press and hold the Restore Key for more than six seconds.

I did the following 1) upgrade the RS507 to 4090c50CB0RS507.CAB 2) Cold start the RS507  (Hold the scan key and install the battery) 3) Scan the Set Factory Defaults barcode in the RS507 Reference manual 4) Scan the HID barcode in the RS507 Reference manual 5) Attempt to pair-----failed with the paired but not connected message described below, 5) Cold start the RS507 (Hold the scan key and install the battery) 6) Attempt to pair---I noticed it changed the pass key and this time it paired I still have some bad behavior if I  cold boot the RS507 after it is paired, but I found that I could correct that by rebooting the ET1 I'll do some additional testing and advise

The RS507 should be updated with the .DAT file (the WT4090 is updated with the .CAB file). Use the PCTOOL application (part of the RS507 update zip) to upgrade the RS507 using a PC..

Hi, you need the latest fw for the RS507 that supports HID and works with iPad and other non-Moto devices. Setting the RS507 to HID will make it works. Regards Pietro

check the following video  http://www.youtube.com/watch?v=oE3pE6ieNnI  . regards, Riad

as Pietro mentioned  make sure that your RS507  firmware is PAAACS00-004-R00 (Latest FW required because it introduces HID pairing with non-MPA devices. Available at support.symbol.com.) one advantage when RS507 paired with ET1 is that the ET1 Soft Input Panel is still available , not the case when paired with Ipad for example .

Try the following: 1. Change the RS507 BT profile to HID or SPP. 2. Disable authentication on RS507 3. Disable authentication on ET1. 4. Retry to pair the devices.
