I turned the power off on all my Bluetooth devices, put them in my car and drove the car down the street. Then I brought my cell phone and a Two Sigma speaker back into the house.
I turned the power on my cell phone on. The phone started and I clicked on Settings, selected Bluetooth. It said “Your phone is currently visible to nearby devices” and it listed devices that the phone had been paired with. I tapped on My Computer and it said “Connecting” and then it said “Connected for call and media audio.” Next I went to my computer and clicked on the Bluetooth icon located on my Taskbar, selected “Show Bluetooth Devices” and it said Devices (1) Samsung SM-G930V. I conclude that my computer is capable of detecting a cell phone with Bluetooth in Discovery mode.
Next I switched the power button on my Two Sigma Bluetooth speaker to On. A blue light came on and the sound signaling Discovery Mode sounded. I went to my cell phone and clicked on Settings, selected Bluetooth and clicked on the icon for my Two Sigma speaker, and it said “Connected for call and media audio.” Then I went to the Main Menu on my cell phone and clicked on Play Music, selected John McDermott and Waltzing Matilda played through my Two Sigma speaker. I conclude that Bluetooth technology on my Two Sigma speaker can broadcast a Bluetooth signal, pair and connect with another Bluetooth device.
Next, I shut off my Two Sigma speaker. Then I went to my computer and clicked on the Bluetooth icon on my Taskbar and selected Show Bluetooth devices. As expected the Two Sigma speaker did not appear since it was turned off. I turned the speaker on and a blue light appeared on the speaker and the sound signaling discovery mode sounded. With the speaker in Discovery mode I went to my computer, I clicked on the Bluetooth icon and selected Show Bluetooth Devices. The Samsung cell phone appeared but not the Two Sigma speaker. I clicked on Add Device and it said “Searching for devices make sure you device is discoverable. “ I waited. The speaker did not appear. I conclude that my computer is not discovering a speaker in Discovery mode.
What is the difference between the Bluetooth signal broadcast by a speaker in Discovery mode and the Bluetooth signal broadcast by a cell phone in Discovery mode? Why doesn’t Plugable’s new Class 2 Bluetooth 4.0 Low Energy adapter detect my speaker? It detects my cell phone.
