carisma protocol, is it possible?

[gr3yh47]

i have a radiomaster mt12 multiprotocol that i want to bind to a carisma gt24. is it possible? i cannot determine protocol

attached is a picture of the chip. below are links to the (quite useless) product pages for the aio i have, a standalone rx with the same protocol, and the tx that the car comes with.

TX: https://carisma-shop.com/products/kd-propo-ctx-2000-2-4ghz-wheel-transmitter?_pos=1&_sid=404a3a6a2&_ss=r#
AIO: https://carisma-shop.com/products/gt24-esc-rx-module-n-version?_pos=3&_sid=2272fdc39&_ss=r#
Same protocol standalone rx: https://carisma-shop.com/products/sca-1e-receiver?_pos=5&_sid=2083c9a22&_ss=r#

edit: someone found these links, they think regarding the same chip. maybe it helps?

The RF component helps to see if it can be emulated with the multi module RF components. But you still have to do the reverse engineering of the protocol. Without having access to the TX+RX there is little I can do unless you plan to do SPI dumps or send me a set.

@pascallanger how can i do spi dumps? i need specialized equipment? I'm a developer/techie/fpv hobbiest so i have a skillset but i've never really messed with anything as low level as the protocol itself.

also i have a transmitter and aio (with blown FET but the rx still works) that i could send you depending on how expensive it is to ship, want to direct msg me your shipping address and i'll see what it would cost me?

Thanks for asking that I encounter same problem
