Notes on Nokia 3650 phones


Information on Connecting a Nokia 3650 to a Linux box is very useful.

The PC connect software (for windows) that comes with the phone seems a bit flakey. It didn't work at all for me until I downloaded the latest bugfixed version from the Nokia website. Even then I was unable to transfer a file directly from my PC to the phone's flash memory without the software deadlocking. (Transferring to the phone's battery backed-up RAM seemed more reliable but still not that good)

Transferring files directly via Bluetooth seems to be the answer. Data received this way ends up in the phone's inbox and then may be copied to the flash. Unfortunately the data must be in the right format or else the phone will not recognise it.

Transferring Digital Audio

The phone's native digital audio format is 16kHz, mono, 16-bit, IMA ADPCM-encoded WAV. To convert an arbitrary WAV into this format on a Unix box use the following command:
sox <input.wav> -r 16000 -c 1 -i <output.wav>
The resulting file can then be sent to the phone by bluetooth and will be recognised by the phone software.
