WiFi Access Issues

[ctag-fh-kiel]

TBD offers two WiFi modes:

• Access Point (AP)
  -- TBD creates its own WiFi
  -- Default with no password, you can set your own SSID name and password through the web ui
  -- Default setting when booting the first time on a freshly flashed module / purchased one
• Station Mode (STA)
  -- TBD tries to join an existing user defined WiFi network with a given passwords (all configured by user through web ui)
  -- If TBD cannot join WiFi network, it switches to AP mode after some time using no password, you can make use of this in case you misconfigured the STA configuration data such as password etc.

Trouble shooting:

• TBD does not join a predefined WiFi network in STA mode -> wait until it automatically switches to AP mode and search for its network, join and reconfigure TBD through web ui
• TBD creates WiFi network in AP mode but you cannot join it -> possibly password of AP WiFi network lost/forgotten -> you can read out the password using a terminal application and the TBD connected through USB to computer, alternatively re-flash TBD with latest firmware
  -- For reading out data through a USB serial connection and a terminal program, connect the TBD with a USB cable to your computer; you may be lucky and a fully web-browser based terminal app like https://www.serialterminal.com/ works (connect to TBD USB port, default baud rate 115200bps), alternatively here ist more information on serial terminals Sparkfun Serial Terminal Tutorial
  -- In some cases, when the TBD serial chip is not recognized by your operating system, you may need to manually install the serial chip drivers on your operating system; older TBD with micro USB connector have Silabs CP2102 chips newer ones with mini USB have CH340 chips
  -- For flashing TBD you need to follow the steps in the main Github TBD repository
