API bug: WifiConfig_GetCurrentNetwork function always returns RSSI value of zero (via WifiConfig_ConnectedNetwork structure)

Question

WifiConfig_GetCurrentNetwork function always returns RSSI value of zero (via WifiConfig_ConnectedNetwork struct)

WifiConfig_TriggerScanAndGetScannedNetworkCount() and WifiConfig_GetScannedNetworks() functions however, both return a valid RSSI value (via WifiConfig_ScannedNetwork struct)

The structs WifiConfig_ScannedNetwork and WifiConfig_ConnectedNetwork are identical, so it appears there is a problem with the WifiConfig_GetCurrentNetwork API?

- Please advise...

Answer 1

Hi Peter,

According to the description, value of zero means success.

See here: https://docs.microsoft.com/en-us/azure-sphere/reference/applibs-reference/applibs-wificonfig/function-wificonfig-getcurrentnetwork

- Definition: Gets the Wi-Fi network that is connected to the device. This function is not thread safe.

...

- Returns: 0 for success, or -1 for failure, in which case errno is set to the error value.

Hello Peter,

We found that RSSI value is now fixed on version 19.05. See more details of the troubleshooting here: https://github.com/MicrosoftDocs/azure-sphere-issues/issues/94
