安卓系统会首先读取BTM_DEF_LOCAL_NAME的值,如果为空,就使用"ro.product.model"作为蓝牙设备名。
system/bt/btif/src/btif_dm.cc
#define PROPERTY_PRODUCT_MODEL "ro.product.model"
......
static char* btif_get_default_local_name() {
if (btif_default_local_name[0] == '\0') {
int max_len = sizeof(btif_default_local_name) - 1;
if (BTM_DEF_LOCAL_NAME[0] != '\0') {
strncpy(btif_default_local_name, BTM_DEF_LOCAL_NAME, max_len);
} else {
char prop_model[PROPERTY_VALUE_MAX];
osi_property_get(PROPERTY_PRODUCT_MODEL, prop_model, "");
strncpy(btif_default_local_name, prop_model, max_len);
}
btif_default_local_name[max_len] = '\0';
}
return btif_default_local_name;
}

#define BTM_DEF_LOCAL_NAME "QCOM-BTD"
