TH05F BLE not working

[Zannys]

Hi, i have 3 this devices, 2 i can work perfectly, but when a flash the third display work ok, but i have no signal for BT, when i flash original FW i can find de device with nFR connect, any ideia?

BOOT is not written.
https://github.com/pvvx/THB2?tab=readme-ov-file#boot-and-app-firmware

The recording sequence is only as follows:

1. python3 rdwr_phy62x2.py -p COMx -e -r wh ./bin/BOOT_TH05F_v21.hex
2. python3 rdwr_phy62x2.py -p COMx -r we 0x10000 ./bin/TH05F_v21.bin

https://github.com/pvvx/THB2/blob/master/wr_th05f.cmd

A separate re-write of fw will break the bootloader layout.
Before writing BOOT, the entire flash is erased, along with the secure boot table.
Writing FW adds data to the secure boot table for the ROM chip. Re-writing FW will break the boot table.
Use BLE OTA after writing BOOT.

Sorry, a forgot to put, but i try only burning boot, and the ABLE not appears, then i tried burning the boot loader and firmware with this two commands in sequence, and nothing

Check the chip's "eFuse" using the extended rdwr_phy62x2.py program.

python rdwr_phy62x2.py -p COMx i

Another version - extended rdwr_phy62x2.py

[Zannys]

sorry, i didn't notice the is another file

There are no restrictions or protections in Efuse.
BOOT firmware should work...

[Zannys]

i will try a older version to check, but is very strange, my other 2 sensors works fine, may be a full erase first?

[Zannys]

just to check, this is normal output for flashing bootloader?

[pvvx]

Yes.

may be a full erase first?

The -e option clears Flash - "erase Flash work area". And this is displayed in the log.

I have this same problem, 7 works good, but one not, do you have any ideas? i made everything from this post but nothing works, i cant connect into TH05F

[vr6racer]

I have programed several TH05 without any problem, but all the 7 TH05Y v3.1 not so much.
I can flash boot v21 and app v21 via cli without erros, but never shows in BLE..
Tried every sugestion but no luck..

what else can i do?

[csorvagep]

I have the same issue, with TH05F v3.1 I can see the BLE device with the original firmware, but it's not there with boot or app.

I also tried to restore the original Tuya firmware, but it shows me E2 now. Maybe that helps to investigate the issue.
