Project #038: PSoC 4 BLE Low Power Startup

BLE Protocol, by design, needs accurate clocks for its operation. To meet the clock accuracy, external crystal oscillators are required in the design. These oscillators do have a finite start-up time, which is inversely proportional to the clock frequency at which the crystal operates.

In today's project, we demonstrate how to reduce the start-up current by configuring the BLE device in deep-sleep mode, 1.2uA current consumption, during start-up instead of the default active mode, >5mA current consumption. For demonstrating this application, an AltBeacon is instantiated in the BLE component that continuously advertises in non-connectable mode with the payload as per the AltBeacon specification.
