I am using chirpstack (lora) server.
Gateway is RAK7243 https://www.rakwireless.com/en-int/products/rak7243/
I have added the following two devices:
#1 - Smart Waste Bin Detector DF702 LoRaWAN http://www.dingtek.com/product/5-en.html
#2 - DO200 Ultrasonic + Magnetic Parking Occupation Sensor http://www.dingtek.com/product/73-en.html
gateway and devices have been activated and i receive uplink data.
data received as base64 encoded and saved in postgres table device_up in column data(bytea)
how can i decrypt this data and get devices data-params accordingly?
