Hello
I build temperature sensor. No i am wondering is it possible to add some additional part to have datalogger,SD card probably , what else? But what about programming? Goal is to store data when no signal from lorawan gateway. When signal return stored data will be sent .
Anyone give me a hint how to achive it?
That kind of solution is in lht65s dragino.
Thank in advance .
Get the normal happy path working first then work on the failure path. Working with SD Cards can be very frustrating. There seems to be so many ways that SD Cards fail or the interface is just not as reliable. I would use SD Card after all other ideas have been looked at.
Temperature data is very small, so you could even store a fair number in memory to send later when the networks is working. If you are storing data, you may need also store some kind of time stamp with the data. The data might not have any value unless you know when the reading was taken.
Anyone tried it on cebucell. Any example please?
