CC3220MODA: AT command errors

Linda Zhang84708

Part Number: CC3220MODA
Other Parts Discussed in Thread: CC3120

Hello Champs,

Customer is using CC3220MODASF and after running "AT+WlanScan=0,5" there was error displayed as "ERROR: process command,-2073".

Would you please kindly help what about the meaning of this error info? how do they write this AT command to get the correct result?

It's the first time for them to use AT commands, they found it confused since there are only commands description in AT command user guide document but no detailed examples and the configuration procedure explained in it.

Would you please help whether the detailed guidance for AT commands is available or not?

Thanks!

Best Regards,

Linda

    AT Commands are a basically a reflection of the simplelink API.

    So most of the error codes (that are not related to AT commands implementation) can be checked in source/ti/drivers/net/wifi/error.h.

    E.g. -2073 is GET_NETWORK_LIST_EAGAIN (#define SL_ERROR_WLAN_GET_NETWORK_LIST_EAGAIN (-2073L)) and it means that currently the scan is in progress and you need to call the command again (preferably with small delay). It will return successfully as soon as the list is available,

    We are familiar with the gap of the examples. AT commands should not be the first choice when selecting the interface to the device. But it can enable a fast bring-up (without driver porting) of the device from an external host and the SDK example can serve as a reference of how the API should be used (basically whenever an SDK app calls an SL command, there should be an equivalent AT command).

    Why did the customer preferred using the CC3220 with AT commands over, for example, using CC3120 (where the driver and examples are available)?
