I have an audio source (portable cd player) connected to an amplifier through the AUX In. At the push of a button (preferably wireless) I need to have a device interrupt the current audio source by lowering its volume and instead feed a pre-recorded message to the AUX In to be played on the Receiver. The message is no longer than 30 seconds. This is similar to PA systems where when the announcers starts to talk the music is lowered. These are my constraint: 1. The solution has to be an existing device (or multiple devices) that integrates with my current setup. No computer solution. 2. I need to be able to easily record a new announcement on the device. 3. The cost should be less than $200.

I have a Bluetooth Low-Energy beacon project that is based on a CSR1010. I have the beacon code working but the beacon function is currently broadcast (transmit) only. Now I need to add the ability to detect (receive) when another paired beacon comes into range. When another beacon comes into range it will trigger a PIO output. Need someone with lots of experience programming CSR BLE chips.

Hello, I am looking for ideas / approached / protocol suggestions on a wireless device implementation. Please do not bid on this if you do not have working experience with this type of network! I will not pay if you do not have real experience! My application has a master base / router to send out ON and OFF commands to the end devices.Each end device needs to be individually separately controllable. The end device is battery powered and controls a light. There is no real data to send upstream, so one way may be an option. The tricky part ... it needs to support 500,000 devices under the same roof. The protocols I have reviewed thus far will not support this many devices. So I am looking for protocol suggestions and frequency bands. Again DO NOT respond if you do not have real, successful, hands on experience! Thank you PS this device does not have to communicate on or over the internet. Additional information: The network topologies is open. I am able to use wired or wireless re...
