take a look of the code and in particular here
for (int i = lineBeg; i < lineEnd; ++i) {
- char ch = reply.charAt(i);
- /*
- * Assume that the signal level starts
with a '-'
- */
- if (ch == '-') {
- /*
- * Skip whatever instances of '-' we
may have
- * after we parse the signal level
- */
- parsingScanResultLevel =
(scanResultLevel == 0);
- } else if (parsingScanResultLevel) {
As you can see it expect a minus. You can obtain it in the
wpa_supplicant response
or just revert this change and don't look for -. Add a print in this
function to see
if it return the list of the wifi network and
good luck
