    I tried to connect the Torpedo wireless module with my phone so I can send it some Serial message using the bluetooth SPP profile. However all the apps I have tried says it cannot connect to the device. Pairing and transferring file to the Torpedo works fine. Transferring files from the Torpedo does not work though.

     

    Any ideas how to add the SPP profile? Do I have to upgrade the TI WL1283 firmware? If so how do one do so?

    My understanding is that RFCOMM is the Serial Port Protocol. (See: http://stackoverflow.com/...ooth-spp-in-android)

    RFCOMM is built into the kernel and upgrading the firmware shouldn't make any difference. Upgrading the firmware would also require a newer kernel driver. We have a backported kernel driver for our Linux distribution with newer firmware, but it didn't get ported to Android.

    Gingerbread 2.3.4 is API 10 (See: https://source.android.com/source/build-numbers.html)

    I would look at https://developer.android.com/reference/android/bluetooth/BluetoothDevice.html and select API 10 from the menu. They have some API instructions for RFCOMM with API10. Let me know if that helps.

    So it works using BluetoothChat program example on android. However it seems a bit unreliable. This might be the android code itself. I will do more test to verify.
