Customers can use Keil to develop ASR6601. Makefile also can be used for compilation and download. For further details, please refer to ASR6601_Quick Start Guide.
Test codes can be found in the directory of projects\${DEMO_BOARD}\examples\lora\lora_test in SDK. ${DEMO_BOARD} is the corresponding board name. For example, ASR6601SE-EVAL stands for ASR6601SE/SER development board, and ASR6601CB-EVAL stands for ASR6601CB/CBR development board.
Please refer to ASR6601_Quick Start Guide for compilation and download introductions.
There are some AT commands built in test codes, which can be used to test part of functions.
Test Command: With one serial port tool, and run AT command AT+CTXCW=490000000,22 to test the power. Please refer to Section 3.2.6 for parameter descriptions.
Reference Result: 21 dbm
Test Command: With one serial port tool, and run AT command AT+CRXS=490000000,0,0,2,0 to test the sensitivity. Please refer to Section 3.2.3 for parameter descriptions.
Reference Result: -138 dbm
