[Q] Nexus 4, Kitkat, android NDK can't access bluetooth - Android Q&A, Help & Troubleshooting

Hello
fellow developers,
I'm trying to access bluetooth trough ndk on kitkat, but keep getting errors. Sample code I'm using.
Code:
int fd = socket(PF_BLUETOOTH, SOCK_SEQPACKET, BTPROTO_L2CAP);
if (fd < -1)
{
sprintf(buff, "socket(...) error: %s", strerror(errno));
return (*aEnv)->NewStringUTF(aEnv, buff);
}
int opt = 0;
if (setsockopt(fd, SOL_L2CAP, L2CAP_LM, &opt, sizeof(opt)) < 0)
{
close(fd);
sprintf(buff, "setsockopt(...) error: %s", strerror(errno));
return (*aEnv)->NewStringUTF(aEnv, buff);
}
const char* bdaddr_src = (*aEnv)->GetStringUTFChars(aEnv, aSrc, 0);
const char* bdaddr_dst = (*aEnv)->GetStringUTFChars(aEnv, aDst, 0);
struct sockaddr_l2 addr;
memset(&addr, 0x00, sizeof(addr));
addr.l2_family = AF_BLUETOOTH;
str2ba(bdaddr_src, &addr.l2_bdaddr);
bind(fd, (struct sockaddr *)&addr, sizeof(addr));
memset(&addr, 0x00, sizeof(addr));
addr.l2_family = AF_BLUETOOTH;
addr.l2_psm = htobs(CTRL);
str2ba(bdaddr_dst, &addr.l2_bdaddr);
if (connect(fd, (struct sockaddr *)&addr, sizeof(addr)) < 0)
{
close(fd);
sprintf(buff, "src: %s\ndst %s\nconnect(...) error: %s", bdaddr_src, bdaddr_dst, strerror(errno));
return (*aEnv)->NewStringUTF(aEnv, buff);
}
(*aEnv)->ReleaseStringUTFChars(aEnv, aSrc, bdaddr_src);
(*aEnv)->ReleaseStringUTFChars(aEnv, aDst, bdaddr_dst);
This works on my HTC Desire Z with android 2.3, but on Nexus 4 I'm getting an "No route to host" on connect(...). I understand that, bluez which I'm trying to use was replaced by bluedroid, but I've compiled bluez from source and included in my app.
Am I being denied access to bluetooth device for some reason, or will bluez not work that way? Can I create a hci connection with bluedroid?
Both my devices are rooted, should I request root privileges somehow?
Thanks in advance, any help is appreciated.
P.s.
Sixaxis works on my Nexus 4, so there's got to be a way.
