Re: 2022 Icon programming cable
So for the ESP32, it talks serial direct to the controller. The controller itself uses a NXP chip which uses the FreeMaster / MCB protocol. It's pretty simple from the comms side and each parameter is just a memory read or a write to set it. The trick is to know what memory address holds what value and what's worse the location of a parameter can change from one version of the software to the next. The nice thing is there's a block of fixed parameters which indicate what software version the controller is running and a version for the parameters which lets the control software change addresses based on the running version.
Anyway, in my case I have the ESP32 lock down the controller on power up so the cart won't move until it detects a bluetooth beacon from a known source. I'm just using a cheap Tile as the beacon and the ESP32 detects the presence and then unlocks the controller. I also have my phone as a known source, so it will unlock on that too. It's simple but effective. |

From there it didn't take long to find the protocol documentation (MCB), which I compared to the traffic across the port to make sure it was correct. |

Re: 2022 Icon programming cable
I think I'll have one available on Amazon soon. Anyone else can obviously sell them. I'm not trying to control the market or anything.
The hard part for any of these cables is mass producing them cheaply and distributing them easily. I've got one finished prototype that I'm going to test next week and verify it works. If it does, I'll order 50-100 sets of components, which takes roughly 1- 2 weeks, then I'll send them to Amazon where it takes them 1-3 weeks to process. If you want to wait for the one I'll sell on Amazon I'd guess roughly 20-45 days before you can 2-day order it. Amazon can be slow to intake stuff. My prototype might not work. Few things could change that number though. |

Re: 2022 Icon programming cable
I bought the device Bobby suggested. And i have purchased the cables you had on Amazon last month before i understood they are for the 2021 models. Does your cable set require any modification that a layman can do?
