CC3200: CC3200 Access Point Mode

Part Number: CC3200
Other Parts Discussed in Thread: CC3220S-LAUNCHXL, CC3220S,

Can the CC3220S-LAUNCHXL demo operate as an wifi access point only?  I'm curious as to its capabilities.  I would like it to run in access point mode as its own private wifi network and then run a simple web page server that a smart phone could look at after connecting to the access point.  What can I expect for power consumption?  Can I achieve low power consumption in AP mode (< 500uA)?

    Hi,

    Yes, you can use CC3220S in access point mode. But power consumption will be much higher. I don't know exact numbers for CC3220, but with previous CC3200 it is about 60mA at 3.3V in AP mode. I suppose that with CC3220 it will be similar.

    Are there any ways to reduce the power consumption in access point mode? increase the time between beacons?

    Hi Andrew,

    Sorry no. Access point mode is very intense to power consumption. Trick with increasing beacons interval is not applicable to AP mode. In access point mode need to be always radio on to be ready serve to clients. If you need low power mode, you need use STA mode (station mode).

    Power consumption is STA mode is discussed here - www.ti.com/.../getliterature.tsp

    Which CCS demo would be best to get me started for developing an access point only demo with a web page server?

    Hi Andrew,

    With CC3220 you not have much options. For this moment CC3220 SDK (version 1.30) contains only few examples. I think you not have more option than start with out-of-box example even if is unnecessary complex. For example in previous generation SDK (CC3200) is example "httpserver" which is ideal for your purpose. Examples from CC3200 SDK are not compatible with CC3220.
