Send never ends
Describe the bug.
Created several datasets for CAME bruteforcing. Up to 50 codes per file Flipper sends the batch and stops. Narrowing down to the 20 per file, it starts sending but never completes, stays in the Send moving waveform screen. Also seems not to send codes since my gate never opens, while it does with the 50 batch file.
Reproduction
- Rename this file .sub and upload to Flipper (github does not accepts .sub) CAME_20_80.txt
- SubGhz=>Saved
- Select the file
- Send
It keeps sending forever. I can use any of the 20 codes files generated by CAME Bruteforcer

Anything else?
Running 0.63.3
Generating lots of 25 and 5 is still fine, completing and working. Something wrong with the 20 lines ones.
I'm fine. starts and starts .... you have a slightly wrong RAW file, it should ideally start at a high level, but this is not necessary
I understand the file is not well formed, will inform the developer of the script. I do not understand if it is necessary to modify the firmware to avoid malformed files to be stuck.
seems to be correct. i just downloaded yours
This specific file does not work with 0.63.3. Also the developer noticed the problem, see issue 3 above on his repo.
Same file, same behavior. It goes in some infinite loop. Other batch sized work fine. No difference at all. Using 0.66.1

Says that he does not have time to read from the SD card. Try another SD card, even though it's stan. Do you have EXACTLY official firmware and not custom?
I can reproduce this issue under some specific conditions, we'll address it in next update
Attached the benchmark. I do not think it is performance related since I have thousands of files on the same SD card and only the ones generated by camebruteforcer in 20 codes batch have this problem. Any other works fine.
I understand this may be a problem with the generator, still Flipper should terminate the loop or say there's something wrong with the file.
Your generator is emitting invalid code: there is an 634691 [E][SubGhzFileEncoderWorker] Invalid level in the stream. But that's not the issue, flipper can handle it.
Closest to what you described I can reproduce by simultaneously uploading big file to SD. We'll focus on fixing it first.
Just to add some bits: I'm not uploading anything while airing that file, Flipper is in my hands disconnected from anything. I can run big batches (4k codes) and small batches (5 codes) with no problems, so that Invalid level must be somewhat related.
Only for that specific file and after several SD formats/writes/rewrites since the issue was opened? An SD that run a Raspberry with no problems? Will try another, I have dozens.
Tried on the fly the shi***est card I have here. 2Gb from dinosaur era. It completes. Attached also the benchmark.
sdcard in SPI mode is something very unpredictable, so even shitty cards may be surprisingly good and vice versa.
Pretty sure it is strange, but I just took out a 16gb from a phone, formatted on the PC and put the contents of the original sd card (zip of the root) and slammed into the dolphin. It plays all the files I tested except the 20-batch ones, like the one from this issue. The SD layout is different since also the file listing now is ordered, the original one does not. So maybe SPI/Speed have a role here, but it is very-very curious that the same file creates the same problem with different SD, different SD layouts, formatted on different devices, still they transmit the other files. To add another test I run the 20-batch while attached to the power and on battery, same result.
Anyway, we'll redesign preload process so it will explicitly tell about any issue like this one.
