Version 0.3.0. Backported network code from experimental roaming project. Will now connect after reset to the strongest AP. Id the signal level drops below -67, extra scans are done to see for a better AP. Nothing is done yet. Removed config.conf file, all info is taken from the project menu and live tests. Better log the board type and send it via json mqtt. Send bssid and current channel too.
