Ad Hoc connection between Android Tablet to Android Phone

Thank you for reading this post. Please check on the attached picture A infrared receiver (similar to the picture) connecting to Android Tablet. Once the infrared receiver detected a signal then the Android Tablet will send a signal by Wifi to mobile phone (Andriod). Once the mobile phone detected a signal, it will make a sound "Beep" and also record and display the time and date when the Beep comes up. The program needs to be record 100 records of the date and time of the Beep and can able to review the records at any time. Just like a spreadsheet. Once the records are over 100, it will do overwrite the old records. What is needed for the Andriod Tablet 1. Create Wifi Tethering function on the Andriod Tablet. Able to create SSID and pasword. 2. Able to accept specific signal from the IR at different [login to view URL] example, if set at accept 500hertz signal then only count for the 500hertz signal. What is needed for the Andriod Mobile Phone: 1. Create program to process the received signal, make a Beep once received. 2. Recording 100 date and the time of the Beep appear. 3. Review the 100 records date and time P.S. For the Andriod Tablet, we can use any version of Andriod OS.
