I have some more specification about our LORATECH node (configurable with microSD card). This node has profi sensor from bosh (pressure, temperature, humidity) + battery voltage and status byte. But the main thing: It wakes up with special circuit every minute (it can be set up in production). After that your config is taken from microSD card - conf. file. It is FAT32 filesystem.
OTAA - mode \space multiplikation 3 \space appkey \space appeui
