» LoRaWAN 07: Channels setting

This example shows how to configure the channels settings. There are 16 channels. The first three of them are always preconfigured and cannot be changed: 868.1 MHz, 868.3 MHz and 868.5 MHz. Besides other parameters can be changed in all channels: Duty Cycle, Data rate range and channel status

Required Materials

1 x Waspmote
1 x Battery
1 x LoRaWAN module
1 x 868 MHz antenna
