[q] fm transmitter app for z ultra???

Spirit Transmit on Play should work on rooted Xperia T and most Z and Z1 class Sony devices with Qualcomm FM chips, like Z Ultra.

Spirit Transmit is based on Spirit2 now. The latest 20150317 release fixes problems with device detection: https://play.google.com/store/apps/details?id=fm.a2d.st

The older v1 of Spirit Transmit, based on the Qualcomm app, is here: http://xdaforums.com/showthread.php?t=1059296&page=845#post55456171

Also the latest 0317 beta releases of Spirit2 and Spirit2 Free have a working transmit mode, although with fewer features than Spirit Transmit.

Spirit2 Free 0317 is here: http://xdaforums.com/attachment.php?attachmentid=3215671&d=1426618705

For transmit mode, set Menu>Set>Tuner>Mode to Transmit and restart Spirit. Not required with Spirit Transmit, which defaults to transmit mode, but can receive (for testing) too.

Copying my post from here for posterity: http://xdaforums.com/xperia-z-ultra/help/z-ultra-fm-transmitter-app-t3057193

Transmit capability in Sony Qualcomm FM/combo chip devices may be an "accident".

To transmit, the so called "Internal Antenna" pin of the chip must be connected to wired headset as the antenna. Most other Qualcomm chipped devices use the "External Antenna" pin which can only receive.

I'm not sure why Sony used the "Internal Antenna" pin. Hypothetically, the electrical characteristics, like impedance, of that ping may have suited the designers better.


But I lean towards the idea that designers wanted to be able to provide an FM transmit ability, while management did not want the extra costs associated with app creation and testing for this.

T-Mobile did this with a phone once; I have a leaked transmitter app and it works on 2 of my now very old phones. They changed their minds.

If nothing else, you can get a phone to market faster without additional testing, and the smartphone market has been fiercely competitive to get their devices out first.
