kellybs1 | 0:2abdab750246 | 2 | This program: |
kellybs1 | 0:2abdab750246 | 3 | - connects to a LoRaWAN by ABP/MANUAL |
kellybs1 | 0:2abdab750246 | 4 | - reads light data from an TSL2561 abient light sensor |
kellybs1 | 0:2abdab750246 | 5 | - sends the recorded data onto the LoRaWAN |
kellybs1 | 0:2abdab750246 | 6 | - sets the mDot to sleep |
kellybs1 | 0:2abdab750246 | 7 | - repeats these operations in a loop |
