This is very useful information - thank you for posting. It does show proof of concept. Do you intend to share any code / guides relating to your efforts, or are you looking to develop a solution to sell?
I’m not a software developer, so i doubt i will make any software as a such. I can promise i will do as much testing work and will share as much technical details as possible so someone who is familiar with software development can create something all of us can use. I can see the easiest way is to use OVMS, they already have some API’s so anyone can create they own apps if they want. It is hard to convince descent developer to do something without proving the concept of making money.
At this time i can confirm that Gateway ECU goes in to sleep shortly after locking the car, blocking access to other ECUs. But i did some testing and can confirm that you can send certain request signal to wake it up again for the short period of time to get the information You require from Your car. After this it will go back to sleep mode.
I noticed today that after successfully pairing my iPhone SE with the MG ZS EV the contacts/sync downloads fails.
Also when bluetooth is connected, plugging in the iPhone with the USB cable caused bluetooth to disconnect. It appears that CarPlay and bluetooth cannot work at the same time...
If anyone can sell me a full size wheel from the MG ZS EV I would be very grateful. I want a full size spare, so please don't lecture me on a space saver!
If anyone could help I would be very grateful and I can pay cash and collect.
