Scope: Added a workaround for 32-character SSIDs by adding a 33-character, null-terminated array.
Addresses: If SSIDs are 32-characters in length (WL_SSID_MAX_LENGTH), networkSsid[networkItem] will not be null-terminated. When printing the SSID, the print function will iterate through the networkSsid array into subsequent networkItems until it encounters the next Null character. (In the case of networkItem=9, the print function likely goes out of bounds until it encounters the next Null character.)
Limitations: While 32-characters SSIDs are legal, this fix uses an additional 33-bytes to work around the issue.
Tested: ScanNetworks.ino compiled and ran successfully on Feather M0 Bluefruit LE and Feather nRF52840 Express with ESP32 FeatherWing.
