CCS/CC3220SF: get RSSI to AP

What other sl_WlanXXX APIs are you calling? I believe this is happening because some other API you used already has the NWP measuring statistics.

Hi,

sl_WlanDisconnect

sl_WlanConnect

sl_WlanPolicySet

sl_WlanGetNetworkList

sl_WlanSetMode

sl_WlanSet

do i need to protect those function by mutex?

Hi,

What simlink doing when i call sl_wlangetnetworklist?

I want to be shure that is will not corrupt other process such mqtt aws and tcp send receive messages from a server

There is a way to get the last message to router RSSI, without all the diagnostic procedure?

Hi,

Using API sl_WlanRxStatGet() you can get RSSI value from the last sl_WlanRxStatGet() API call. In case this API is returning error code, you need to have something significantly wrong inside your code design.

Btw ... it not make sense call often than at interval 5 sec. Because it will not be returned proper RSSI value.

Example how to read RSSI:

SlWlanGetRxStatResponse_t rssiRxStat;
int rssi = -99;

if (sl_WlanRxStatGet(&rssiRxStat, 0) == 0) {
  if (rssiRxStat.AvarageMgMntRssi != 0) {
    rssi = rssiRxStat.AvarageMgMntRssi;
  }
} else {
  rssi = -99;
}

Hi,

I implement in my project mqtt tcp aws and get the rssi each 5 sec, therevis a problem with that?

Do i need to protect the  sl_wlan...  api with mutex?

Hi,

Any socket code like MQTT should not affect sl_WlanRxStatGet() API call. You don't need to protect sl_WlanRxStatGet() API by mutex. But generally it not makes sense call concurrently  sl_Wlan API.

Hi,

What are you recomended to use to get rssi and what period ?

Hi,

Any interval, but not fastest then 5sec.
