Describe the bug

Hello, i'm trying to use it on sony z3 compact, so i installed lineage 14.1 and installed bluetooth.default.so for nexus 5 as it has the same broadcom chip, but when i try to use connect command i get error.

Hardware and operating system

Sony z3c with lineageos 14.1 from https://volatilesystems.org/dl/lineageos/14.1/z3c/ and this bluetooth stack https://github.com/seemoo-lab/internalblue/tree/master/android/lineageos14_1_hammerhead .

To Reproduce

Logs or screenshots

I found that the problem is with internalblue/utils/packing.py so i updated u8 function to this:
def u8(num, endian: str = ''):
print(num)
if endian.lower() == 'big':
return struct.unpack('>B', num)[0]
elif endian.lower() == 'little':
return struct.unpack('<B', num)[0]
if (type(num) == int):
num = bytes([num])
return struct.unpack('B', num)[0]

but i often get errors like this on android logcat:
01-16 05:46:00.951 15136 15169 E bt_hci  : command_timed_out hci layer timeout waiting for response to a command. opcode: 0x41d

Hi @jurek4321,

definitely looks as if something goes wrong there. To debug if it is the bluetooth.default.so I can recommend just using plain Wireshark. Usually, if Android/Lineage loads the module correctly, you should see Android debug interfaces in Wireshark even if not calling it via InternalBlue, and you can select the BT Snoop Log. Looks like this on my Nexus 5:

You might need to turn off/on Bluetooth once after a reboot before it works.

Once you connect with InternalBlue, you should see a version command (because that's the first thing InternalBlue does to determine the correct firmware file), and you should also see the contents of the packet when or before it breaks.

@unixb0y did some changes to the adb part lately but AFAIK he tested everything on the Nexus 5.

If you see stuff in Wireshark but not in InternalBlue, I can do some debugging these days and check if the new adb implementation works on both macOS and Linux hosts.

Best,
Jiska

[jiska2342]

Ah, and maybe one thing I should add:

If InternalBlue gets the correct firmware version answer, it will send a command starting with 0x7, which enables diagnostics, instead of 0x1, which are the usual HCI commands. Sending 0x7 might still succeed, but if the bluetooth.default.so driver is patched incorrectly, it might later on fail to parse the diagnostic information and just crash somewhen during parsing packets. That might be the error, since you're actually getting a crash within the Bluetooth daemon. But it might also be InternalBlue sending something completely unexpected.

Thanks for replay, how i can get correct patch to build bluetooth stack for z3c?
In wireshark i see packets like "Bluetooth HCI Event - Hardware Error" and next "Bluetooth HCI Command - Reset"

[jurek4321]

I tried to build it for z3c but when i run "breakfast z3c" i get following error:

Hi @jurek4321,

building the module properly is somewhat complicated and I did that a loooong time ago :(

I just realized that the debugging method with Wireshark in parallel doesn't seem to work, at least not with my setup, because the socket seems to be exclusive. However, that depends a bit on the precise setup.

This is how the output looks like on my Nexus 5 with the most recent version of InternalBlue:

Depending on what you want to do you can also work around via InternalBlue instead of fixing your Android bluetooth.module.so compiler errors.

Workaround 1: Use the serial TTY interface within Android instead of modifying the driver.

For this, you can call InternalBlue with the -s parameter, which in turn calls the following code:

internalblue/internalblue/adbcore.py

Line 347 in 070f828

def _setupSerialSu(self):

Note that I did not test these commands on Android 6, only on 8-10. Thus, you might need to adapt them. But in general, you can always echo raw bytes into the Bluetooth serial interfaces. Forwarding this via netcat etc. is just much slower than changing the driver module.

You cannot enable the DIAG mode like this, because then you'd still get messages that are either ignored by Android or crash the driver. DIAG mode is the 0x7 thing that later on enables you to see the LMP traffic etc.

Workaround 2: Disable DIAG

Assuming that your recompiled driver works (or the one you downloaded from here) except from diagnostics, you can also just remove this function:

internalblue/internalblue/core.py

Line 2157 in 070f828

def enableBroadcomDiagnosticLogging(self, enable):

Hope that helps you on the way to fixing your issues :) And good luck with compiling Android ;)

Best,

Hi @jiska2342, I successfully build bluetooth.default.so for z3c, but i still have the same problem that i have with ready build bluetooth.default.so for nexus 5. When im trying to receive with lmp monitoring enabled im getting errors in logcat and bluetooth is restarting:

Do you have any idea why its still not working and how i can fix it?

[jiska2342]

Hi @jurek4321 ,
Android has minor versions. For example, Android 6.0.1 has multiple releases for the Nexus 5 (see https://source.android.com/setup/start/build-numbers). Most likely, you're using an incompatible pre-built bluetooth.default.so. And yes, it might work a bit if you're using the wrong version, just as your log shows, but fail later on.

[jurek4321]

@jiska2342 , i know that it may not work, but as i wrote before i build bluetooth.default.so for z3c. I build it for lineage 14.1 and i'm using it with lineage 14.1. So it looks like patch for nexus 5 is not working with z3c. Is it possible that patch for nexus5 will not work with z3c? Did i need to change something it patch?

[jiska2342]

Most likely, you will have to build bluetooth.default.so from scratch for your device and the correct LineageOS version. There are too many combinations of hardware and Android versions to provide pre-built Bluetooth drivers for all of them :(
