Function Documentation

decodeCurrentTime()

bool ersa::protocols::decodeCurrentTime ( const uint8_t *  value, size_t  size, uint32_t &  epoch  )

inline

Decode the Bluetooth SIG Current Time characteristic (UUID 0x2A2B).

CTS reports local calendar fields rather than an absolute timezone-aware instant. The returned epoch encodes those fields in a UTC-shaped number so the watch RTC can preserve the wall-clock time shown by the phone. This function validates the complete 10-byte field set and has no BLE dependency, allowing malformed values and leap dates to be checked on a host.

Parameters

value	Pointer to the characteristic bytes.
size	Must equal the specification's 10-byte structure size.
epoch	Receives encoded seconds only on success; unchanged on failure.

Returns

False for null, wrong length, invalid calendar fields, or overflow.

readLe32()

uint32_t ersa::protocols::readLe32 ( const uint8_t *  p )

inline

Decode a four-byte little-endian integer from a validated input buffer.

writeLe32()

void ersa::protocols::writeLe32 ( uint8_t *  p, uint32_t  value  )

inline

Encode a 32-bit integer as four little-endian bytes into caller storage.
