Answers checklist

• I have read the documentation ESP-AT Programming Guide and the issue is not addressed there.

What is the expected behavior?

The +CWLAP response conforms to the documented format here

+CWLAP:<ecn>,<ssid>,<rssi>,<mac>,<channel>,<freq_offset>,<freqcal_val>,<pairwise_cipher>,<group_cipher>,<bgn>,<wps>

What is the actual behavior?

The +CWLAP response contains () brackets around all parameters. This does not match the documentation and breaks the general API format of <cmd>: followed by comma separated parameters. Having the parameters bracketed means it does not conform to the format of other API commands and has to be custom parsed.

Example:
+CWLAP:(3,"TEST_NETGEAR26",-54,"22:6d:34:30:7f:72",11,-1,-1,4,4,7,0)

it is this way a very long time now. it would be a breaking change if the {} are removed

[JHedgesBartec]

Authorised personnel should then update the documentation to reflect actual behaviour

@JHedgesBartec @JAndrassy Thanks a lot! We should update the ESP-AT document.
