I have a RAK 7205 mounted on a vehicle in a farm lorawan setup. It was reporting intermittently for about a week then stopped reporting altogether. I’ve since connected to it via usb and it has now jumped back to life, however even when left in the same spot in direct sunlight in the backyard it continues to miss sending observations. Currently i have it configured to send every 10 mins. Please see the attached graph that shows how often it managed to report over a 3 hour period.
Q. If the device wakes up and fails to get a GPS satellite fix should it still send a lorawan packet? i.e my expectation would be to see a packet every 10mins or so with some being error readings if the device failed to find a satellite.
Q. Any tips for how to debug what is happening here? When it is indoors and connected to my pc i can’t seen any obvious error conditions. I would like to be able to check if it is successfully waking up every 10 mins, if so is it failing to get a satellite fix etc.
Q. Assuming sunny conditions and the solar panel is operating at max capacity what would you expect to be the max frequency you could send observations without running the battery flat? i.e is every 10mins to often?
Q. Basically i was hoping to recreate a ‘strava (iphone app)’ like experience where i would have enough data to map where a vehicle had been and how fast it was going at different points during the trip. My ideal scenario would be reporting sensor observations as often as every 5 seconds while the vehicle is in motion. Is this type of usecase supportable with the RAK7205?
