I would try upgrading to V39 but it will not stay connected long enough to change the settings!!!

You can do that manually by following the appropriate steps in the manual, you just need to connect it to a USB port on a computer and get it into bootloader mode as described.
HA2NON Ok, makes sense. So should I increase the RX timeout time on the REF/XRF connector settings? Do you have a recommendation?

Try decreasing the keepalive interval value and increasing the RX timeout value.
