![]() ![]() When trying to connect to COM9 RealTerm successfully connects but doesn't send any data over BT (or the Raspberry doesn't receive - not sure), and this weird thing: TXD "pin" remains always ON until I disconnect: When trying to connect to COM5 RealTerm throws me the following error, so can't do any testing using this Outgoing COM port - I've also tested using TeraTerm - same issue, won't open the port: Now on W10 side I'm using RealTerm tool and I'm trying to connect to one of the new two COM ports that were created after pairing and connecting to Raspberry: ( COM5 - Outgoing, and COM9 - Incoming) - not sure which one should be used so I'll just try both of them. On Raspberry side I first set the BAUD rate associated to /dev/rfcomm0 port to 19200 using this command: stty -F /dev/rfcomm0 19200, then I start a terminal session on this port using the screen tool: screen /dev/rfcomm0 19200. Now I want to test the BT communication between this two devices, and I want to pass some messages using terminals. On the W10 machine I now now have this following setup: I did the scanning, pairing and trusting using the bluetoothctl utility, then I used the rfcomm utility to create a COM port ( /dev/rfcomm0) on Debian side: sudo rfcomm connect hci0 38:FC:98:47:05:67 - W10 automatically connected and it's looking like this: I successfully paired and connected from Raspberry (using a SSH terminal) to a Windows 10 machine (Surface 3 tablet). I have a Raspberry PI 3 model B, with built-in Bluetooth hardware, and I'm running the latest Debian distro on it (Linux raspberry 5.15.61-v7+).
