Ai-Thinker TB-04 disabled

[mwitkow]

Hi, got the following TB-04 kits: https://www.aliexpress.com/item/1005002767348600.html

I belive it's this chip: https://docs.ai-thinker.com/_media/ble/docs/tb-04_product_specification_en_v1.0.pdf

however, i'm getting:
22:10:35: Searching for devices.
22:10:47: Waiting for connection with Ai-Thinker.
22:10:49: Invalid device selected!
22:10:49: Device disabled.
22:11:04: Search for devices

Despite pressing prog for 1s

Another option:
Connect the TX output from the USB-UART adapter to the SWS module and use USBCOMFlashTx.html

Description can be found here: https://github.com/pvvx/ATC_MiThermometer?tab=readme-ov-file#the-usb-com-adapter-writes-the-firmware-in-explorer-web-version

If the module has a standard program, then TelinkOTA may work.

Firmware from Ai-Thinker usually has its own program for the programmer:

According to TB-03F-kit schematic pin 2 from CH340 is connected to TL A0, i.e. line RXD from TB-03F, which is also on goldpins J2 (pin 12). Wouldn't be easier to connect SWS to RXD (J1 pin 3 to J2 pin 12) using jumper wires instead of soldering a wire to CH340?
