Clone a HT-640 remote (Holtek 40 bit) with Arduino using Flipper capture

Sub-GHz
#1

Hi all,

My Flipper was able to capture and emulate a remote with a HT-640 chip (Unsupported protocol: Holtek (e.g. HT-640), also used in Linx remotes) without any issues.

I would like to build a clone of this remote using Arduino with an RF module. I tried to capture a signal with Arduino, using a receiver module and RCSwitch, but it does not recognize the 40-bit holtek protocol.

I have both RAW signal capture file and the flipper-recognized “Holtek 40-bit” file, both work with Flipper. Any ideas how I “feed” the Flipper Sub-GHz files to Arduino?

Thank you.
