Renting Project #29

Closed zstergios closed 5 years ago

Hi, I'm web programmer and 2 years I have spent some time with arduino and electronics. Your project it's lifesaver. My client wants to rent the scooter like LIME etc.

I can build the APP, the communication api between CONTROLLER->SERVER->MOBILE and backend for management.

I know that there are chinese options out there that I'm thinking it's worth tring to make a demo controller my own.

Still I don't have any Xiami scooter to my hands to able to digg but I'm making a research to be prepared of what I will face.

So, let's start, please help if the following are right conclusion or wrong

1) There 2 power lines 5v & 48v (or 36v), so I don't need regulator to 5v

2) As I read here, the board controller has some pins for output (TX/RX etc) so arduino can write/read via serial

3) firmware.ino seems that I can get/set readings for almost all common renting combabilities

4) Xiami has his own Bluetooth connection. As I know only registered devices (owner) can connect If not I should disable it.

5) Has some space near to the board controller to add my custom PCB

6) 5V line has over 2 Amps current

Some considerations I would like to use something that I have worked before like arduino. But has few space, GPS+GSM+ code may it will not have enough ram to do the POST requests. The other solution is to create a PCB with 2 arduino (bear bones) to double the space & ram (more tricky)

The Bluetooth is not secure at all and you should absolutely disable that. With that, one could easily replace your main board and walk with your scooter.
