I want my wan 1300 to wake up once a day at a pre-defined time and send the data to my LORAWAN network. the project needs to run on battery. what deep sleep modes can i use ? i want the wan 1300 to only connect to LORAWAN over OTAA once and then just keep sending data once a day. Can i maintain the LORAWAN counters and session keys in sleep modes ? how to best achieve this kind of functionality.
can anybody help
If you sleep only, data is retained. If you want to physically switch off the board, look for a flash storage library or EEPROM emulation library to save data on the flash memory (not too often!).
