7.3. Hardware Failure
If the Hardware fails the LEDs can flash in a pattern to determine the type of failure. The power
LED will flash the pattern if no LEDs are present on the downstream ports.
The unit will blink four times, followed by eight long or short flashes, which then repeat. The
flashes are a number in binary which match a number in our error code list.
i.e if the LED flashes the following - BBBB SLSSSLSS, the binary number is 01000100.
7.4. Device connection.
If you are having device connection issues please read through the following common solutions
to see if this resolves your observed behaviour.
Unstable device connection
Some devices can have unstable connections with your host system through the SP54. We have
only observed this behaviour in a very few amount of devices, by disabling CDP this has
resolved all issues and the connections are stable.
You can disable CDP through NVRAM settings either by going through the advanced settings
and turning "Alt Sync charge" off or through the API and disabling it via code. For example,
using the command line, the instructions would be as below.
settings_unlock
settings_set sync_chrg 0000000000000000
Battery information for Android
If you are having issue displaying battery information on Android devices ensure firstly you
have ADB tool installed and open then try these things in order.
1. Check that developer options are enabled on the android device, and then that USB
debugging is also enabled.
2. If you have done this step and it still does not work, go to Developer Options and click
'Revoke USB debugging authorisations'. Unplug the cable and reconnect.
