19 Returns Analog-to-Digital Converter (ADC) pin status report. If the ADCP parameter
is set, the reports returns GPIO pin state. Otherwise, it returns the ADC value only.
ADC value=<level>, GPIO state=<state>
I/OK
where
• level is an integer in the range 0-255 representing the input voltage measured on the
ADC pin, calculated as follows: (A/3.3V)*255=level, where A is the analog input
voltage.
• state indicates the state of the output GPIO pin: 0 (High) | 1 (Low). GPIO state is
reported only if the ADCL, ADCT and ADCP parameters are set.
For example, if the ADCP parameter is set:
ADC value = 255, GPIO state = 0
I/OK
If the ADCP parameter is not set:
ADC value = 255
I/OK
20 Returns a list of all APs and ad-hoc networks available in the surrounding area.
Each line contains the following comma-separated fields:
<SSID>,ADHOC|AP,<BSSID>,<securitytype>,<channel>,<RSSI>
I/OK
where
<security type>=NONE | WEP | WPA | WPA2
<RSSI>=|SNR+NoiseFloor|
