I’ve had the Sodaq SSF for a while, but had to put the hobby project to a side for a while.
I’ve also got the Sodaq ONE and this is working well for me via LoraWAN. It sends out a update very 5 min and charges via solar. It’s been doing this for around 6 months now, which is awesome.
I want to try to get the same setup but with the SSF and over mobile network. I know that this will be tricky because of battery usage.
I’m using the Sodaq Universal Tracker (GitHub - SodaqMoja/Sodaq_Universal_Tracker) and have made some modifications for myself for the LoraWAN implementation.
I’ve now loaded this onto the SFF.
I’m using a hologram SIM card at the moment and use the R412 radio which is 2G. The reason for this is that where i want to deploy this device, there’s no NB-IoT or LTE-M yet.
What i’m struggling with is how long it takes for the SIM card to get a network. It can take a few minutes and with the fix interval set to 1 minute (for testing) i tend to get an update every 4 or 5 minutes. That means the device is constantly “on” and doesn’t go into sleep mode at all, which is a problem for battery power usage.
I’m wondering if others have the same experience, and if there’s a way to make this work faster/better.
