zhou2008 There are Bluetooth serial modules for sale on Taobao, which can be paired with a computer and then connected via Bluetooth. For example: It can be directly connected using software. I'm not sure if it can also be used for writing audio.
BG5VLI My personal opinion is that this module might be directly forwarding received data packets. Clarifying the TX and RX definitions for 'k' header could potentially help.😂
BG8LGP This is definitely achievable; the K5's K-head line definition diagram matches exactly with what "建伍" has: Furthermore, you can use the relevant Python code from GitHub to create a Bluetooth writing software, which will enable Bluetooth writing.
ReadAir BG8LGP Hello, I've been searching for a definition of this K-header, and the diagram shows 6 lines. Why can I only find examples online with 5 cores?
zhou2008 After adding the Bluetooth serial module, I can now use my computer to control the frequency via Bluetooth!
ReadAir BG8LGP When searching for "K-head" cables, I can only find these types, which have either four or five cores. However, the cable labels are missing the R segment with a 2.5mm connector, and I'm not sure what the internal structure of the write-enable line between one end of the K-head and the USB port is like. Could it contain a CH340 chip or something similar?
BG8LGP ReadAir I understand that this is a pre-wired kit, designed to make it easy for you to connect the chip and create the write-in line directly. The specific wires to connect are shown in the diagram I posted above.
Yuluoxk ReadAir Yes, inside the frequency line, there is a CH340 chip. When connected to a computer and checking for serial devices, you will see an additional CH340.
ReadAir BG8LGP It seems like I can't use it for writing a frequency line. This cable, once connected, can only be used for speaker output or voice input. The small R-end is not connected, and neither is the serial TX end. So, I don't think this will work?
Yuluoxk Since Bluetooth can be used for this purpose, could it also be possible to create an application that uses Wi-Fi for writing firmware or upgrading? I have a large white Dragon Sparrow Tech Bluetooth and Wi-Fi board that I'm planning to try out.
