Empty historical data for wireless AP

[amirnetop]

Hi, 

I'm currently using the following AP to read historical data for signal quality for of my APs

networks/{networkId}/wireless/signalQualityHistory

I'm attempting to read timespan of 8h back from current time in a resolution of 300 secs (making a call for a specific AP so in the URL I'm only sending: deviceSerial, timespan and resolution)

As a result I'm getting back lots lines with empty RSSI and SNR like the following example:

{'startTs':'2023-08-23T00:00:00Z'

'endTs':'2023-08-23T00:05:00Z'

"snr":None

"rssi":None}

(few lines are not empty and contains actual real values)

Q1: why do I get empty data back?

Request: I need historical data for AP SNR and RSSI but it's very problematic to make a cal for each AP, is it possible to extend API to return all the data for all the AP in a network?

Hi @amirnetop, 

In regards to the APs that are not displaying SNR and RSSI values, what model AP and firmware version are they running?
