I guess I'm in the right place with my question. Actually, I have several IoT e-scooters from old brands that discontinued several models; some have issues. I have an Okai ES400B Gen 1, the oldest rental model ever made. I acquired it from several owners, and it's in really good condition. The scooter has a ZK115L IoT, and it's working. I know the e-scooter uses CAN. However, I want to edit some settings but can't because the 4-pin USB connector is gone, and I don't have the port password. My question is: is there a good replacement that non-commercial users can buy? Everything I've seen online requires commercial status. Or is there a DIY way to access this? I know there are some professionals in this forum, and I hope to hear from you.
