TTN Mapper Configuration
TTN Mapper is a convenient tool used for mapping the network coverage of gateways connected to The Things Stack. Check the official TTN Mapper documentation site for more details.
This tutorial will guide users to add the SenseCAP T1000 Tracker to TTN Mapper.
In order to explore the next steps, please refer to Connect to The Things Network to register your device first.
Configure the Payload formatters
Create a Custom JavaScript formatter and copy the following code.
