2018-04-24Convert our custom IO model to new libdivecomputer IO modelGravatar Linus Torvalds
This converts our old custom IO model to the new model that libdivecomputer introduced. This is partly based on Jef's rough patch to make things build, with further work by me. The FTDI code is temporarily disabled here, because it will need to be integrated with the new way of opening devices. The ble_serial code goes away entirely, since now libdivecomputer knows about BLE transport natively, and doesn't need to have any serial wrapper around it.

2018-03-13Subsurface update for upstream libdivecomputer changesGravatar Linus Torvalds
So because I merged with upstream libdivecomputer, and it no longer does the "halfduplex emulation" thing in the IO layer, and instead does it in the only Suunto backend that needed it, that also affected our custom IO layer in subsurface. Sure, I could have left a dummy interface and left subsurface with some ugly dead code, but it's really better to just get rid of the code. So when Dirk pulls in the libdivecomputer updates from https://github.com/torvalds/libdc-for-dirk.git Subsurface-branch this patch to remove the halfduplex code in subsurface is also needed.

2017-09-22BLE: big writes to connected DC (OSTC firmware)Gravatar Jan Mulder
Most writes to a connected DC are small, typically some command bytes to get DC in download mode, or to set some parameter. All this just worked over BLE, however, sending a full firmware update (on an OSTC device) failed, as the underlying BLE interface can only handle small 20 byte BLE packets at once. So, send max ble->packet_size chuncks at once. Tested for the following cases (linux desktop with OSTC3 over BLE): 1) normal download of dive data. 2) read and write settings from configure UI 3) update firmware (from 2.15 to 2.15) And to my surprise, no flow control credit administration is required here.

2017-07-19BLE serial read/write bufferGravatar Jan Mulder
The adapted define was confusingly wrong. Apparently, the BUFSIZ define was coming from some include file, and was dependent on platform (Linux 8K, Andorid 1K). Simple rewrite to a new define and a proper value for both Linux and Android. If 4K is big enhough, is a little uncertain, as its depends on the read behavior of all libdivecomputer parsers using this serial BLE interface. The buffer size needed (on read, as that is the most prominent direction when interfacing with DCs) is (most likely) 2x the maximum block the libdc parsers request at once. I did not study all parsers, but the Shearwater parser request 20 bytes at once (we know that from the 1 packet at the time read, we had before). The OSTC parser request 1K blocks for data that is longer than 1K (like profiles, header tables). The 1K we had on Android was working for Shearwater, Eon Steel, but not for OSTC,as its reads 1K at the time at max, and overflowing the buffer. So 32k or 64k seems way to big (as in, much bigger than any libdc read). Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
2017-07-11OSTC over BLE: read a long as neededGravatar Jan Mulder
See also b409e9fc91d87bbd5 and 709c1df2af4b87. The OSTC parser cannot handle reads of single 20 byte BLE packages in serial mode. Instead of doing a deeper down agressive read, we can read on the serial level more subtile. As the parser is requesting a specific number of bytes, we just read that number of bytes and return them. As the 20 byte BLE packets do (obviously) not align with the reading requirement of the libdc parser, a little housekeeing needs to be done in between individual reads. CAVEAT 1: In contradiction to 709c1df2af4b87, this is supposed to work for all parsers that properly specify the needed bytes to fetch. CAVEAT 2: All above tested on Linux Desktop with bluez stack. Subsurface mobile is step 2. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>

2017-06-27Switch over to SSRF_CUSTOM_IO v2Gravatar Linus Torvalds
I hate changing the IO interfaces this often, but when I converted the custom serial interface to the more generic custom IO interface, I intentionally left the legacy serial operations alone, because I didn't want to change something I didn't care about. But it turns out that leaving them with the old calling convention caused extra problems when converting the bluetooth serial code to have the BLE GATT packet fall-back, which requires mixing two kinds of operations. Also, the packet_open() routine was passed a copy of the 'dc_context_t', which makes it possible to update the 'dc_custom_io_t' field on the fly at open time. That makes a lot of chaining operations much simpler, since now you can chain the 'custom_io_t' at open time and then libdivecomputer will automatically call the new routines instead of the old ones. That dc_context_t availability gets rid of all the if (device && device->ops) return device->ops->serial_xyz(..); hackery inside the rfcomm routines - now we can just at open time do a simple dc_context_set_custom_io(context, &ble_serial_ops); to switch things over to the BLE version of the serial code instead. Finally, SSRF_CUSTOM_IO v2 added an opaque "dc_user_device_t" pointer argument to the custom_io descriptor, which gets filled in as the custom_io is registered with the download context. Note that unlike most opaque pointers, this one is opaque to *libdivecomputer*, and the type is supposed to be supplied by the user. We define the "dc_user_device_t" as our old "struct device_data_t", making it "struct user_device_t" instead. That means that the IO routines now get passed the device info showing what device they are supposed to download for. That, in turn, means that now our BLE GATT open code can take the device type it opens for into account if it wants to. And it will want to, since the rules for Shearwater are different from the rules for Suunto, for example. NOTE! Because of the interface change with libdivecomputer, this will need a flag-day again where libdivecomputer and subsurface are updated together. It may not be the last time, either.

2017-06-26BT serial: recognize LE-only devices, and fall back to emulated serialGravatar Linus Torvalds
This is somewhat hacky, but it allows at least the Shearwater libdivecomputer backend to continue to treat even the BLE GATT model as just a serial protocol. What it does is create a special "emulate serial behavior over the packetized BLE protocol" helper layer, that qtserialbluetooth falls back on when rfcomm is not available. NOTE! This still requires some BLE packet code changes to work with the odd way that Shearwater sets up their BLE GATT communication. So note that no further patches are necessary to *libdivecomputer*, but some updates are needed for the subsurface qt-ble.cpp code. I have those updates in my tree, and this code is all tested on my Perdix AI, but those patches are currently too ugly to commit as-is. I've cleaned up this "fake serial" code sufficiently, that cleanup comes next. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-06-24Very early and likely quite broken BLE GATT codeGravatar Linus Torvalds
This is some very early and hacky code to be able to access BLE-enabled dive computers that use the GATT protocol to send packets back and forth (which seems to be pretty much all of them: a vendor-specific GATT service with a write characteristic and a notification characteristic for reading). For testing only. But it does successfully let me download dives from my EON Steel and my Scubapro G2. NOTE! There are several very hacky pieces in here, including just "knowing" that the write characteristic is the first one, and the notification characteristic is second. The code should actually check the properties rather than have those kinds of hardcoded assumptions. It also checks "vendor specific" by looking at the UUID string representation, and knowing that the standard ones start with zero. Crazily, there doesn't seem to be any normal way to test for this, although I guess that maybe the uuid.minimumSize() function could be used. There are other nasty corners. Don't complain, send me patches. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2017-06-22Convert to new libdivecomputer custom IO modelGravatar Linus Torvalds
Instead of being "custom serial", it's a IO model that allows serial or packet modes, independently of each other (ie you can have a bluetooth device that does serial over BT rfcomm and packet-based communication over BLE GATT with the same serial operations that describe both cases).

2017-05-31Android BT download: hardcode UUIDGravatar Dirk Hohndel

2016-09-17Rewrite libdivecomputer custom serial codeGravatar Anton Lundin
This rewrites the custom serial code to use the new api which I implemented in the Subsurface-branch of libdivecomputer. This is a bit to big patch but I haven't had the time to break it down into more sensible patches. This rewrite enables us to support more ftdi based divecomputer communication and is tested with both a OSTC3, OSTC2N and a Suunto Vyper, all over the libftdi driver. The bluetooth code paths are tested to, and should work as before. Signed-off-by: Anton Lundin <glance@acc.umu.se> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2016-04-04Move subsurface-core to core and qt-mobile to mobile-widgetsGravatar Dirk Hohndel
Having subsurface-core as a directory name really messes with autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an autocomplete conflict and also was inconsistent with the desktop-widget name for the directory containing the "other" UI. And while cleaning up the resulting change in the path name for include files, I decided to clean up those even more to make them consistent overall. This could have been handled in more commits, but since this requires a make clean before the build, it seemed more sensible to do it all in one. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
