Just got my NExT implanted last week and have been having a blast setting it all up.
For the HF side of the chip, I am storing some encrypted backup text and would ideally like to make the implant read only, with a password required to overwrite the data. This would basically be a sanity check to avoid me accidentally overwriting the data unintentionally.
I found this thread Can my xNT be easily set to read-only? - #2 by amal referencing the xNT and I believe I have figured out the default password on the NExT, however, when I try and send the second and 3rd lines of hex I just receive an NAK response. Below is what I am sending and receiving:
TX: 1B xx xx xx xx
TX: A2 E3 04 00 00 04
TX: A2 E4 00 00 00 00
When I send an intentionally invalid password, I receive an ‘NAK’ on line 1 as well, so I believe this means the password is correct.
Anyone have any pointers?
