Hello,
I have successfully connected to a BLE HID (peripheral) device and /dev/hidraw1 file is created. I am able to read raw data successfully from hidraw1. However, when I try to read a feature report from this device, the Bluetooth service crashes. The bluetooth service log and my source code are below.
Enviroments:
------------
Linux Mint-17 KDE
Kernel 3.13.0-24-generic
BlueZ 5.21
Output of Bluetooth service:
----------------------------
# bluetooth -d -n
...
...
bluetoothd[2610]: profiles/input/hog.c:forward_report() Sending report type 3 to device 0x000C handle 0x1C
(bluetoothd:2610): GLib-ERROR **: /build/buildd/glib2.0-2.40.0/./glib/gmem.c:103: failed to allocate 4294967295 bytes
Source code:
------------
void foo()
{
uint8_t buf[3];
memset(buf, 0x0, sizeof(buf));
m_DevReadWriteHandle = open("/dev/hidraw1", O_RDWR);
...
buf[0] = 0x04; // Feature Report ID
ioctl(m_DevReadWriteHandle, HIDIOCGFEATURE(sizeof(buf)), buf);
