WIP: Use "D-Bus over TCP/IP over Ethernet over BLE" for communicating with the watch #216

Open I-asked opened 6 months ago

I-asked commented 6 months ago

Hi @FlorentRevest! What a coincidence indeed… (We came up with the same idea within the span of two weeks :flushed:)

Sooo this is my attempt at replacing ATT-based comms with something more streamlined (D-Bus). :v:

The session bus is exported over TCP to the companion for seamless event transfer between the two devices.

A simplified version of asteroid-tap2ble forwards packets from a TAP interface over BLE. (since the link is relatively slow [26 kbps avg.], we should stick to lightweight protocols, so D-Bus-over-TCP, 9p, etc.; SSH is sadly way too bulky for this connection.)

The packets should then be handled on the companion in an appropriate manner.

To achieve this on Android, I am using libslirp, which allows me to create a virtual network adapter that translates Ethernet packets into unprivileged calls.

To do

Currently working on the MediaService (MPRIS), also updated dbus-java locally.

I believe the 14-bytes Ethernet frame can be shaved down to 1 byte for point-to-point (a pair of nibbles for source + destination MAC)

@I-asked I've been testing your PRs, great work! But I'm wondering what kind of performance we can expect? Currently pinging seems to take some time:

I've tested this with sturgeon and sparrow. Since you mentioned dbus spam I also tried an older version (97694fefe87db358140643272396c23c44224a5d) but that seems to perform similarly.e

Oh my… that is very weird… This should not happen… I can't work on this right now, but the network connection worked very well last time I checked… Could you try a different Android phone?

@I-asked I've been testing your PRs, great work! But I'm wondering what kind of performance we can expect? Currently pinging seems to take some time:

I've tested this with sturgeon and sparrow. Since you mentioned dbus spam I also tried an older version (97694fe) but that seems to perform similarly.e

Oh my… that is very weird… This should not happen… I can't work on this right now, but the network connection worked very well last time I checked… Could you try a different Android phone?

Indeed very interesting! I've now tried on another phone it where it works much better:

For reference the phone showing terrible results is a Samsung Galaxy S23 Ultra (Android 14). The phone with proper looking results is the a Xiaomi Mi5 (LineageOS with Android 11).

The difference in performance is enough to actually successfully connect to ssh (via the phone)

I-asked commented 3 months ago

Perhaps the Samsung has some weird "battery saving" feature you could try disabling?

MagneFire commented 3 months ago

We already prompt to disable battery saving. Maybe this isn't enough on Samsung. Or maybe it's something with newer Android devices? What phone did you test this with?

I-asked commented 3 months ago

Is the Samsung connected to a wi-fi network? Could you try those two phones both over cellular and wi-fi?

I-asked commented 3 months ago

I last tested on my Xperia 1 IV which was running A13.

MagneFire commented 3 months ago

There appears to be no difference when I use WiFi or cellular.

I've slightly altered your version before the dbus library change and the additional dbus services as there have been a some SDK updates which result in runtime errors. This version is available here: https://github.com/MagneFire/AsteroidOSSync/commits/slirp-2/

Attached are the logs for both phones: mi5.log s23.log

Interestingly D-Bus connection seems to also fail on the Samsung phone.

MagneFire commented 3 months ago

Here are some logs with a little more debug information.

There are clear large gaps visible when looking at the timestamps. Maybe it's some retry logic that has a different timeout?

mi5-2.log s23-2.log

MagneFire commented 3 months ago

Not entirely sure why but it seems that on the Samsung phone the SlirpService freezes in one of the synchronized blocks. Removing these blocks results in a segfault, which is probably due to threading issues.

Replacing the synchronized blocks with conventional ReentrantLock locks solves the freeing issue. Finally changing the resetMtu() function to handle lock acquire issues solves the networking issue and now it seems to work fine:

MagneFire commented 3 months ago

Hmm, after more testing it seems to be related to MTU. The app requests 247 (which is initially also used for libslirp). But once connected the MTU changes to 515. Which results in a libslirp re-initialization with the new MTU. At this point communication seizes to work (ping doesn't respond).

If the requested MTU is 515 it all seems to work fine, but in this case the libslirp re-initialization does not occur. Forcing a libslirp re-initialization (by overriding mDevice.getMtu(); to always return 247) results in the same communication issues.

Next I'll try these things on the known working phone (Xiaomi Mi5, Android 11) to compare if it behaves identically.

Tested on the known working phone. It seems that the MTU doesn't change once connected, it stays at 247. To find out if the issues is with MTU or libslirp re-initialization I've changed the default MTU to 515 and request a different MTU (247) upon second connect, which results in a libslirp re-initialization. Letting libslirp re-initialize results in the same issue as with the other phone (ping not working/very large ttl). Communication works fine when the libslirp re-initialization isn't executed (Thus using MTU 247 with a BLE MTU of 515).
