Now, it’s time to reconnect your transmitter micro:bit and start radio-broadcasting navigation commands for your cyber:bot.

• Reconnect your micro:bit to USB.
• Click the three dots   ⋮   by the Send to micro:bit button, then select Connect.  Then, set up the connection to the transmitter micro:bit. 
• Click Show serial.
• If you do not see a user prompt, press and release the micro:bit’s reset button.
• If you still do not see the prompt, click Open, select terminal_bot_controller_wireless. and click Send to micro:bit.  Then, click Show serial again.

Next, repeat the tests you typed into the app when it was tethered:

• Type 25 in response to the Enter right speed: prompt, then press Enter.
• Type 25 in response to the Enter left speed: prompt, then press Enter.
• Type 750 in response to the Enter ms to run: prompt, and press Enter.
• Verify that your cyber:bot rolled forward for about ¾ of a second.

If you take a look at the dictionary that was displayed, it should contain {'ms': 750, 'vR': 25, 'vL': 25}.  Remember from the Dictionary Primer, order does not matter for dictionaries because they keep the correct values paired with the correct keys.

• Next, try -25, -25, and 750.  Did it roll backwards?
• Now, try 25, -25, 750.  Did it pivot to the right?
• Try 25, 10, 750 for a curving motion.
• Can you make it turn in place left and right?
