When I displayed serial data on my LCD, only the text from the USB connection appeared. Another oddity was that the baud rate on my serial terminal didn't have to match what I set in the program. I wondered if it could auto-negotiate speed, and if that was the case, was I transmitting incorrectly to the Bluetooth module. I connected a USB ↔ serial adapter in place of the wireless module, but I couldn't get a signal. I searched online for a solution and found that, unlike an Arduino Nano, the Micro uses Serial1 for the 0/1 pins, which was great news because that meant I could monitor through a computer while sending commands to the HC-05 units.
I changed my code to send data to the correct serial port and saw an "OK" response. I added the rest of the pseudo-code steps and implemented a new function that checked for the "OK" response after each command. Lastly, I wrote a new process to check for the HC-06 module I selected, and when it sees it, I send the order to connect. Once connected, I write a message that tells how long it took to establish a link. The times I saw ranged from nine seconds to fifteen seconds.
