  1. Although two independent Tibbo BASIC/C compiled binaries (apps) can be stored in the WS1102's flash memory, only one can run at a time.
  2. Several of the WS1102's configuration parameters are stored in the DCB, which is accessible via a new integrated console. Our BLE Terminal web app leverages the Web Bluetooth API (compatible with the Chrome, Chromium, Edge, and Opera web browsers) to connect to the WS1102's console. Configuration properties can also be read and set through Tibbo BASIC/C code.
  3. TLS is supported on a single outgoing TCP connection.
  4. To enable Wi-Fi debugging, you must enable autoconnect — automatic association with a designated Wi-Fi network. This can be accomplished via the integrated BLE console or in code.
  5. The TX and RX line of the debugging UART are connected to the DTR and DSR lines of the serial port. When the serial debugging is enabled, these lines cease functioning as the DTR and DSR lines. To avoid occupying the DTR and DSR lines for debugging, use wireless debugging instead. The debug mode can be selected via the integrated BLE console or in code.
  6. The WS1102 is compliant with the IEC/EN 62368-1 safety standard in the –40°C to +85°C range. To maintain this compliance in the field, use an external DC power source outputting 0.5A @ 9VDC ~ 18VDC (less than 15W) that is also IEC/EN 62368-1 certified and can operate in the –40°C to +85°C range.
  7. Tested according to procedures I, II, and III of MIL-STD-810H Method 501.7 and MIL-STD-810H Method 502.7.
