Hi guys,
I am working on a school project where we will use a nexus tablet to control a toy Pikachu that talks and moves. The system will only need one way communication; no feedback. I got a HC-05 breakout board from:
http://www.ebay.com/itm/HC-05-Bluetooth-Transceiver-Host-Slave-Master-Module-Wireless-Serial-6pin-/221303627009?pt=LH_DefaultDomain_0&hash=item3386b95d01
When it arrive I hooked its ground to my arduino uno's ground, the 5v to my Arduino 5v supply, and the TX to my RX Arduino Pin. I powered the Arduino up and was able to view my HC-05 on the tablets Bluetooth menu. I then disconnected the HC-05 and worked on some other aspects. Later I hooked the HC-05 up that same way and it would not be found discoverable. Thinking I broke the board I got another one from the same location and it still is not discoverable. Does anyone have any idea whats going on?
Both HC-05 boards blink like they are discoverable.
AT mode does not return an OK when sent the AT command.
I am ordering a different brand since they are so cheap because time is crucial.
