Hello . Please answer me, I have cp2102, FT232RL, and DSD TECH USB RS232 to 3.5mm Serial Cable with FTDI FT232RL Chip 6FT.
I have a conversion from 2.5mm to 3.5mm, but it does not work at all. But in the cp2102 and FT232RL it works, but not completely, as it receives data without sending the firmware download. What is the solution ? This is an attached file that shows how to connect the phone with the CP2102 and Ft232RL modules, and another picture showing what results appear to me. Please reply to get the answer on how to send the firmware download successfully!
For your information, I have 3 Motorola devices, C118, C115, and C139. They all have the same result
