content: I'm trying to identify this series of JL Bluetooth ICs while I wait for some modules from China.They all start with AS20BP0xxxx.Does anybody have a datasheet, just a pinout is OK as well.My main thing is a "connected" pin to toggle VCC used to control other things.My old modules had them but have been raised in price and are becoming more scarce.Here are a few module part numbers:

content: I don't see anything that qualifies as a (TSOP?) 24 except theAC6907Aand who knows if it is or not....China likes to hide the datasheets.Hopefully there will be someone that can shed some light on these ICs.I hate to have to wait a month+ to find out.

content: Is something like TSOP24 or QSOP24.When received you can compare pinouts vs some schematics to identify what IC is.And datasheets are really simple,just some basic info for example likehttps://cdn.datasheetspdf.com/pdf-down/A/C/6/AC6905A-Jieli.pdf

content: Yes I understand, but the idea was to have the info before they arrive. I need to start designing the "power on toggle" to a PCB.

content: Well the modules are in and I didn't see the page 2 of the link you provided.looking at the PDF onhttp://www.chenbingdom.com/uploadfile/201721417233513763.pdfI found the typical 6905A schematic. My version is pinning out to this one. My question is could it be an OTP part or in the picture below, is there a way to either access it through SPI or the USB. If USB, what would be the IO voltage? It appears to be 5V. I already have the CSR programmer so I'm not worried about the SPI port as the programmer will do 1.8V and 3.3V. Any smarter folks than me here that can give me a clue as to the point of attack on this module? Thanks.Quote from: gabiz_ro on 2021-03-26, 16:32:56

content: Not sure about 6905A but when I search for some info,some time ago,I remember that I see somewhere something about firmware.Do something on USB (send command or some pattern of hi-lo on data pins) and switch chip in programming mode.I'll try to find it again and post link,but was on russian or chinese site.That's what I found looking in browser historyhttps://blog.csdn.net/JaLLs/article/details/85222667https://radioskot.ru/forum/11-14227-38https://github.com/christian-kramer/JieLi-AC690X-Familiarization

content: Thanks, but I saw all of those links.The Jim link was hard to understand and his software links don't work.I think Russian one didn't explain too much.Both of the above are in the readme.md ofhttps://github.com/christian-kramer/JieLi-AC690X-FamiliarizationAfter making a PDF of it, and reading many words, I found that in the last line he says that he wasn't able to upload the firmware to the moduleEven this reading and document PDF'ing has not cured my insomnia as it is 02:47 local time and I still can'tagain.Perhapstomorrowlater today I'll play again with some USB software and see what the readback is.

content: Thanks I did already see the Reddit posts. Half of the stuff leads to dead links even the Wayback Machine has no archive of.However that lastarchive.ziplooks very promising! More software tools to try.Thank you for helping with this.If I ever do find a way to make any software/hardware work, I'll share/post all the info here.Quote from: gabiz_ro onTodayat 17:14:47

content: Hi!I know that this is an old thread but here are my two cents to it:I have ordered pack of 10 Bluetooth adapters and Bluetooth chips (QSOP-24 Package) on them have writing: AS23BP1F938-65A4.My suspicion after quick search on the web is that digit's after AS on them, represent manufacturing year and relevant part is after “-“ dash.Here is official manufacturer github side with lots of information, firmware and tools:https://github.com/Jieli-TechRegards,P.S. I think my AS23BP1F938-65A4 is AC6965A chip with 4 Mbit Flash memory " A=QSOP-24 Package" and "4=4 Mbit Flash memory" thast the definitions of "65A4" after “-“ dash."Jerry Bluetooth audio chip AC6965A, equipped with a high-performance 32-bit CPU, the chip comes with 4M-bit flash,Support: MP2, MP3, WMA, APE, FLAC, AAC, MP4, M4A, WAV, AIF, AIFC; 10-segment sound effects can be adjusted;Jerry's Bluetooth headset chip AC6965A is compatible with V5.1+BR+EDR+BLE; the Bluetooth headset chip is packaged in QSOP24."Belov is Seller description of an item and pictures where I order it from:"VHM-314 Bluetooth Audio Receiver Board Bluetooth 5.0 Mp3 Lossless Decoder Board Wireless Stereo Music Module 10Pcs"

content: OK, I had relegated this project to the dust bin.I will have to pop this off the project priority stack address where it was buried at a very deep level.Thanks I will look further at the GitHub files, but the naming conventions are vague at best.Thanks for the update it's never to late in a post where info is concerned, just at an awkward time to instantly jump back on the project.

content: Never did! I got really busy and opted for the cheaper option of the next China version with BT 5 #3.I was trying to detect either a voltage level shift to do switching with the older version #2 and instead opted for a messy switch instead.I get so busy I have to move forward, but I do have a few #2's I may try later.The #3'sat startjust yack away as they boot up.The #2's at start had a Windows USB plugin sound 30dB over the program level.Nothing appears to be just right with these things that I would call perfect for the 2.3 cents that it would take to make them right from the factory in the beginning....Quote from: rhodo on 2024-11-17, 16:03:21>Hi Quarlo have you figured out how to program the chip at all?
