SetupPersistentWiFiConnection not connecting to network #63

Closed alidekker closed 2 years ago

alidekker commented 3 years ago

Setup: ESP 01 directly connected to PC with USB-Serial converter. Flashed the ESP 01 with firmware from ESP8266_AT_LoBo GitHub repository. Checked the installation by issuing a number of AT commands and changed for test the baudrate with AT commands. All went well. /Tools/ChangeATBaudRate, /Tools/CheckFirmware and /Tools/PrintPersistentSetting all went well. The problem came in /Tools/SetupPersistentWiFiConnection where no connection to the network could be established. I tried my 2 internal networks and an Android hotspot. It seems that there is perhaps a too small timeframe for the connection to be established and its timing out too soon so I put a -while-not-connected statement- in, to no avail. A number of other examples depend on the persistent WiFi connection so here I am.....stuck. It will be my mistake but please enlighten.

WiFi.begin only returns after joining AP or fail. while-not-connected only makes sense for the automatic connection with persistent settings.

try to clear the flash system parameter area. with esptool write blank.bin at 0xFE000
