to know it's not just hte same xcat thing with a different sticker on it. For every byte I type into the bluetooth side RealTerm, I get 3 bytes out at the USB end, like the two db9 ports are talkign different languages, but htey are all configured to 115200 baud, 8N1, no hardware handshake, so no reason to be different.īelieving my first buetooth-serial adapter to be garbage, I bought another from adifferent brand, with different shape, internal antenna vs big bendy antenna etc. I have done aloopback test on one of them, which passes, but it cannot talk to a usb-serial adaptor, even with nullmodem adapter in between the twoĭb9 ends. I have two different db9 serial-bluetooth adapters now, and neither accomplish this as far as I can tell. Reboot if needed, collect data, install new files etc. What I want to do is to use an embedded system serial port login for maintenence access, see the bootup log which remote system puts onto db9 serial port, later gives a login prompt that I would like to login to and then be able to check on the system, initiate So, which port should we connect o in order to use a terminal program (such as RealTerm) to communicate with some remote computer over serial port login connection?

In below image Com-Port-34 is for Outgoing SPP connection, but how to issue the connection request? but I don't want to use the APP.Īre there any settings on Windows Bluetooth settings, where I can make PC/Dongle to issue the Connection request for the SPP connection? I can see the com ports are getting created after the pairing is done, but SPP-connection is not getting established.Īlso, I used Bluetooth-Serial-terminal App for Windows PC and it can establish the SPP-connection and send/receive data. For this PC shall issue connection request for SPP profile. I want to establish Serial-SPP-connection with my remote-device(Bluetooth Serial adapter). My remote-device(Bluetooth Serial adapter) will always be acting as Bluetooth SPP slave. I have made sure my Bluetooth dongle and the remote device supports SPP profile.

I can see two virtual com ports are getting createdīut PC is not getting connected to the remote-device(Bluetooth Serial adapter) over SPP profile. I can successfully pair with my serial adapter using the settings>BluetoothDevice>AddBluetoothDevices tab. I have connected Bluetooth dongle to my Win-10-PC. I am trying to connect my Bluetooth serial adapter(remote device) to Windows-10 PC over Bluetooth for data transfer over SPP profile.
