BQ3050: bq3050 BootROM mode and .senc file

Part Number:BQ3050

Hi,

I wanted to access the .senc file for bq3050. Therefore, I used the bootROM mode (0x0f00 command) in order to download the .senc file.

Following that I loose communication access to my battery after refreshing and cannot regain access with the 0x08 command that I found in the forum to unable bootROM mode.

Could you help me how I can reestablish communication?

Also, is there a way to actually read the encrypted .senc file? I wanted to find and confirm the used ChemID of our device.

Thanks so much in advance,

Sabrina
