Hi,

I'm trying to unseal the battery using the Advanced Comm I2C Screen but the mode doesn´t change.

I`ve seen that using the UNSEAL command it sends 0x36720414, so i'm trying writting the following commands:

I have readen in the forum other people using that command but it doesn´t work to me.

Sorry about my english. Thank you.

Hello Andres,

It looks like you may not be sending the right commands in order to unseal manually. Also your gauge is already unsealed, it is not in unseal full access though. You can see the lock with the green cross indicates it is unsealed.

This FAQ may be helpful, the addresses may not be the same since it is for a different gauge, but the sequence is the same:
