This guide will help to do initial setup to a Dragino LSN50v2 node: Power on and UART connectivity.
1. Pin Mapping
v2.0: GND, PA2 and PA3 for UART connection.
v2.3: Extra pin GND, PA2 and PA3 for UART connection.
2. Connect UART cable
Turn on the battery power and connect to UART cable
- Connect to UART USB (baud rate 9600): RXD-PA2, TXD-PA3 and GND-GND
- Connect the yellow jumper.
Notes: To connect to extra pins PA2, PA3 and GND in v2.3 for easier access.
3. Connect to UART console
Step 1: To open a UART console
- You need to install a driver for UART USB at common-helper-programs
- You need to install and configure Tera Term at common-helper-programs
Step 2: To open Tera Term and check if the frequency plan is AS923-2 for Vietnam.
- No password is required.
- Reboot: ATZ
- Show all configurations: AT+CFG
Step 3: To check for LoRaWAN information.
- DEUI: Node ID. Must be unique.
- Required for OTAA: APPKEY.
- Required for ABP: DADDR, NWKSKEY and APPSKEY
- APPEUI: May or may not required by the server.
Done.
