5.2.3 BLE Sensor Beacon Operation
This section provides detailed information on the BLE sensor beacon process.
5.2.3.1 Complete BLE Sensor Beacon Process
The complete BLE sensor beacon process invokes running the Beacon_GappStartAdvertisement(). The following waveform
shows the BLE advertisement states.
5.2.3.2 Power Up and Software Reset
The code from the Solar_BLE_Sensor PSoC Creator project is started. This code begins with low-power startup functions.
This allows the system to conserve power during clock startup, especially the WCO, which takes 500 ms for startup. This is
crucial to allow the project to survive on solar power.
The code is optimized to read the USB detect line (P3.5 of EZ-BLE) and immediately switch to UART mode if it was not
detected.
