The Yabby3 is a highly configurable device. Many parameter options are available so that setup can be tailored to suit specific use cases, or enable features.
For many use cases, the defaults are a great starting point, but there are a few parameters which users should pay attention to and configure in order to optimize the performance and battery life of the device.
For optimal battery life, it is important to set the network profile in admin parameters.
The network profile sets the LTE-M and NB-IoT bandmasks on the device. Most networks only use at most a few bands. Setting the bandmasks means when trying to connect to the network, the device will only scan these bands, rather than all possible bands - saving a lot of energy.
See Setting the Network Profile - LTE-M/NB-IoT devices for instructions on how to set the profile, and create a template to apply to all devices.
If you are unsure on which profile to set, contact support.
- Device wakes up and attempts to get a GPS Fix
- If after 15 seconds, we can't even see 1 satellite at all (even with weak signal), give up
- If after another 5 sec (20 sec total), we can't see 2, give up
- If after another 5 sec (25 sec total), we can't see 3, give up
- If after another 5 sec (30 sec total), we can't see 4, give up
The idea here being that if we can't see even a couple of satellites early on, we're probably undercover where we won't get a fix even if we spent 60-120 seconds trying, so we should quit the attempt.
This will save battery life in the majority of cases, but it could cause issues acquiring fixes in some scenarios, in which case the Advance GPS Settings should be adjusted.
