I am using SL8084 for 3G modem only. And I want to run some AT commands to setup system.
But I found a lots of AT commands are always error returns, especially the commands which start from “W”, e.g AT+WHCNF, AT+WFM, AT+WHWV, AT+WUSB … … are all failed. But as I checked AT command set, these are supported.
Here are the running environment:
– Sierra Development Board with SL8084 module and SIM was inserted.
– GPRS attached successfully and link setup completed.
– USB connection to run AT commands
– Firmware Revision: S3_0_0_1AP R1096 CNSZXD00000132 2011/09/22 21:06:44
Anybody can help me to see what’s happened.
