The manufacturer of the pressure switch does not have an API and understandably would not release their proprietary code. I want to be able to write a custom sketch to run on a separate ESP32 to connect and talk to the pressure switch. To be clear, I do NOT was to overwrite any software running on the pressure switch ESP32. In order to develop this custom sketch, I need to know what data or commands are being sent to and from the pressure switch.

    The objective of the project is to create a device using a microcontroller (Arduino) with a NFC device capable of communicating with a 1st Android Phone. The microcontroller with the NFC device will send a message to the 1st Android Phone and will receive a message from the 1st Android Phone. The microcontroller with the NFC will then send the 2 stored messages to a 2nd Android Phone. The sending and receiving of the messages will be done through the NFC device to be connected to the Microcontroller and the NFC devices of the Mobile Phones. The preferred NFC device to be connected to the Microcontroller is the PN532 and the preferred Microcontroller is the Mega.
