Hi, this is not an issue but I would like to know if there is a way to replace the voice alerts on the hw-770 module for something less annoying.

I think this will be a nice improvement has a lot of users on internet hates that voice.

Thanks.

This is not an isuue.

I wanted to show my appreciation and thank you for sharing information about these chips.

Hi, looks like there are quite a lot of smartwatches based on JL701N BR28 however there is no public SDK on their github.
Only the bootloader project supports it.

Do you have more info about that one? Maybe you possibly have access to the SDK for the JL701N watch devboard?

The DaFit mobile application has ~900 watches based on JL701N in its database. One example is Zeblaze GTS 3 https://zeblaze.info/gts3.html with firmware update available here
https://qcdn.moyoung.com//files/DHdJG80gtjagB3ezS9WoHyN81jdeddtN.ufw
Currently it is $8-$15 watch on aliexpress https://www.aliexpress.us/item/3256806229302356.html

here is some random info I found

Do you know why they omitted 701N chips at https://gitee.com/Jieli-Tech ?

Was thinking about custom firmware for those Dafit watches like we currently have for nrf52832/40 DaFit watches. nrf52 is OK but sadly smartwatch manufacturers moved away from nrf5x platform.

One crucial question is whether the firmware is somehow signed/encrypted or custom FW via OTA is possible without having the signing key, can you guess from moyoung download above whether there is chance to modify and reupload that file? I see you have some ghidra stuff, maybe you also know how to unpack ufw file?

EDIT: forgot some links
official one for 7012 with some specs https://www.zh-jieli.com/product/showproduct.php?id=33
here some random documentation using 701N as example https://doc.zh-jieli.com/Tools/zh-cn/mass_prod_tools/private_data_auth/tools_modification_section.html (despite no other SDK or documentation published for 701N)
commit adding JL701N to bootloader Jieli-Tech/fw-Bootloader@40dc675 plus some dual bank update Jieli-Tech/fw-Bootloader@8efd17e

I'm trying to modify my cheap Chinese Bluetooth speaker with JieLie chip (AC6965E i presume) but i found no info about how to program this damn thing, only your guide on the older version.

I'm trying to modify its starting sound, connect, disconnect and low battery sound into something less ear splitting. And hopefully reprogram it to do something more useful (like notify connected devices).

A few extra questions:
How to dump the whole flash to make a backup?
Does the AC6966B SDK work with this?
Does the BR25 firmware structure the same as BR17?
