bool - true if data was returned, false if receive buffer empty

Example

#define BUFSIZE  100
uint8_t buf [BUFSIZE];

// note generic version of call (DRV_BT instead of DRV_BM71) is used
if (DRV_BT_ReadDataFromBLE(appData.bt.handle, buf, BUFSIZE))  // if data received
{
    // do something
}

bool DRV_BM71_ReadDataFromBLE(
