ESP32 PSTN dialer (uk), audio player and bluetooth receiver. The project uses an ESP32 to communicate to a custom ble bluetooth button, which then generates dtmf tones (dials the phone number) waits for the receipt to pick up and plays a sound file. Which will be a short message "The bluetooth switch has been pressed, press 1 to acknowledge" and repeated for up to 30 seconds. If the user doesn't pickup or there are to many "rings" then the esp32 hangs up and dials the second number. The same with up to 5. The esp32 also stops dialing the next number if the receipt acknowledges it with a command code. Initially there is one switch, but future two may be employed. Phone numbers, priority, ring options, acknowdge code and out of range (loss of signal of the ble device) option are to be programmed using a simple android application over bluetooth. The esp32 system will have an led/buzzer if the battery is low in the bluetooth switch it will show this. Hardware to utilise an ESP32 and essential PSTN connectivity. Ideally coded in Ardunio but Espresso is possible. Main functions: Pair with switch Recieve BLE command switch command Dial pre programmed number via android application Play audio messages until acknowledgement Hangup.
