28 Access Sensor Technologies UPAS User Guide
Proceed to update the firmware on any/all UPAS Samplers you have. Then
power Off all UIPAS Samplers. At this point you are done using the computer.
The following steps use your mobile device only.
Special One-Time Update Process
The following extra steps should be done ONE time only. Do not perform the
following steps on future firmware updates (beyond rev102 firmware).
1 Power-On one UPAS Sampler at a time, leaving all other UPAS Samplers
Powered-Off. This helps avoid confusion.
2 Use the mobile App to connect to the UPAS in the normal fashion.
3 If you cannot find the serial ID of your UPAS in the App list, the firmware
update has scrambled the UPAS Bluetooth ID as you updated from
firmware older than rev95. In this case, do the following one-time steps.
Otherwise proceed to step 4 below.
a Use the mobile App to connect to the one incorrect serial number that
shows up as a high 4-digit number (such as PS4489), all zeros
(PS0000), or something odd like MS0+), etc.
If using an Android mobile device that has never connected to the UPAS, use
the Bluetooth menu to pair to the device first, again via the strange ID - and
then connect to it from within the mobile App.
b Once connected to the UPAS with the invalid Bluetooth ID (verify the
LED on your UPAS is cyan/light blue), enter the actual/correct 4-digit
numerical ID (i.e. the ID on the back of the UPAS) into the Sample Name
field in the App, followed by the tilde (~) symbol. For example, for UPAS
PS0123, enter 0123~ in the SAMPLE NAME field and then SET it.
c Start a brief sample run by selecting START, and okay/approve.
d Power-Off the UPAS any time after the light turns red and pumping
begins.
e Power-On the UPAS and wait for the boot-up sequence to complete
(UPAS status light displays solid pink).
f Use the mobile App to connect to the same, invalid Serial ID one more
time; as soon as you connect to the invalid ID, it should change to the
updated ID. This verifies that the prior steps were successful. If the
correct Serial ID does not display, repeat steps a through e above, or
contact Access Sensor Technology (support@accsensors.com).
Otherwise proceed to the following step.
4 Assuming that you are now connected via the mobile App to the correct
serial ID, enter RESET# (all-caps) into the SAMPLE NAME field, and SET it. It
should return to the main screen showing RESET (without the # character)
in the SAMPLE NAME field. You should now see the refreshed BATTERY
CHARGE and BATTERY VOLTAGE displayed (look for changed values vs.
