I have more than 20 vehicles with the tft 100. My goal is to set up the TFT100 so that it enters a power-saving sleep mode when external power is lost (e.g., when the motorcycle battery is disconnected), with the ability to wake up periodically, send its coordinates every 2–3 hours, and then go back to sleep to conserve the internal battery. This is critical for my use case: if the motorcycle is stolen and the external battery is disconnected, the device currently remains in its normal operating mode and drains its internal battery in just 5 hours. I need a solution where it can last much longer while still providing periodic location updates.
I’ve reviewed the sleep modes available in the TFT100 documentation, including Online Deep Sleep, but it seems limited to accepting SMS commands without GPRS functionality, which doesn’t fully meet my needs. Additionally, the configuration examples I’ve found suggest reconfiguring the Ignition Source (e.g., tying it to “Power Voltage”) to trigger sleep modes based on external power status. However, my current Ignition Source is set to detect the motorcycle’s ignition state (via a digital input), and this logic is essential for my application—I don’t want to change it.
Could you please advise if there’s a way to achieve the following without altering my existing Ignition Source settings:
The TFT100 detects the loss of external power (via “Power Voltage” or another method).
After a configurable timeout (e.g., 5 minutes), it enters a sleep mode (such as Online Deep Sleep or another suitable mode).
In this mode, it wakes up every 2–3 hours, sends its coordinates via GPRS, and returns to sleep to save battery.
