OTAA LoRaWAN module

This function block describes the LoRaWAN communication with external LoRaWAN module. The communication between the platform and this module is UART. The UART port on the platform is hardware to the first instance (e.g. UART0). The authentication mode is OTAA mode only. This is Class C (continuous) LoRaWAN communication only.

name type default min. max. description
Target I 0 0 0 The LoRaWAN target module. Default to 0 (WIO-E5). 0 for Wio-E5.
Mode B False None None The connection mode of LoRaWAN. 0 for OTAA, 1 for ABP. Default to 0 (OTAA).
Region S EU868 None None Region Parameters of LoRaWAN communications. Default to "EU868". The options are: "EU868", "US915", "CN779", "EU433", "AU915", "CN470", "AS923", "KR920", "IN865", "RU864", "STE920".
REPT I 1 1 15 Unconfirmed message repeat time. From 1 to 15.
RETRY I 3 0 254 Confirmed message retry times. From 0 to 254.
