LoRaWAN 07: Join ABP send confirmed
This example shows how to configure the module and send packets to a LoRaWAN gateway with acknowledgement.
Required Materials
1 x Waspmote 1 x Battery 1 x LoRaWAN EU or US or AU or IN or ASIA-PAC / LATAM module 1 x 868/900 MHz antenna
Notes
- It is strongly recommended to execute the necessary configuration example before using this code - This example can be executed in Waspmote v12 and Waspmote v15
