Trouble-shooting Registration and Telemetry
Green light is not illuminating when RAPT Pill plugged in to USB-C
This occurs if the battery is below a minimum charge level. Please leave the Pill connected for 30
minutes to gain sufficient charge, then unplug and reconnect.
Red (battery) light flashes rapidly when plugged in to USB-C
Please install the battery or check that it is making good contact with the terminals.
Lights turn off immediately when disconnected from USB-C
Please check the charge level of the battery
–
it may be insufficient to power the Pill. The battery
may be faulty, or not making good connection to the terminals. A fully charged battery has around
4.2V
–
this can be tested with a multimeter. If the battery has a good charge level, gently bend the
terminals out in order to ensure there is good contact with the battery.
Battery level reads 0%/not displaying in the RAPT Portal
The battery needs to reach a full charge when installed in the Pill and connected via USB-C. If the Pill
has not determined the fully charged state then it will not display the correct percentage. This will
normally rectify itself after the Pill is used and then fully recharged.
The lights on the Pill stop flashing shortly after it is unplugged
This is normal behaviour. There is an approximately 10 minute timeout after the Pill is unplugged.
There are no lights on the Pill when unplugged
This is normal. The Pill will be ‘asleep;
by default and will wake briefly at the set interval to send
telemetry. The green light will flash briefly when this happens.
Cannot access the Pill Captive Portal
This can only be accessed when the Pill is plugged in to USB-C. Access to the portal will cease after
10 minutes and the Pill will enter a sleep state. Unplugging and reconnecting to USB-C will allow it to
be reconnected.
