@mardy I have the Redmi Note 9 Pro since yesterday. Since I have to go back from Android 11 to Android 10 anyway, I will download this global version V12.0.3.0.QJZMIXM. Everything else that has to do with the radio I will do at a later date. I tried to get the Redmi Note 7 Pro but no chance.

The Redmi Note 9 Pro works as well, but you need to get a couple of binaries into your vendor partition. I created a script to do it, but it's for advanced users only

@mardy I'll get that somehow, still have to wait until the bootloader is up. If not, I know there will be radio sometime in the future. I still have my radio app, luckily it works somehow. But I'll try your script first. If I've already read everything, 2 files have to be copied.

Hey @mardy, I modified the vendor partition like on Redmi Note 9 Pro for my Poco X3 NFC, which I ported myself and noticed that the FM radio only works after setting vendor.bluetooth.soc to cherokee (It's empty on my device) manually. I could create an overlay for my port which sets that property, but I don't know if it's the best idea or is there something wrong with the FM service?

Wow, good work!! The fm-radio service explicitly checks for that property to be set to cherokee, but that's just because I saw that the qualcomm FM radio app does the same. You could try to run a getprop on the device and see if there's some other property which can be used to identify the bluetooth/radio chipset, and then I could add it to the fm-radio-service. Or, indeed, setting that property in the vendor partition would be a solution.

@mardy Found it. It's called vendor.qcom.bluetooth.soc on my device.

phablet@ubuntu-phablet:~$ getprop|grep cherokee
[vendor.qcom.bluetooth.soc]: [cherokee]

OK, I'll update the service to check that property too.

Hi @ungeskriptet, could you please give a try to the fm-radio-service package at https://ci.ubports.com/blue/organizations/jenkins/UBportsCore%2FFM radio service/detail/MR-4/1/artifacts?

Please write your feedback as a comment to https://gitlab.com/ubports/core/fm-radio-service/-/merge_requests/4

@mardy one can install all userspace tools by submitting ubports-qa install PR_fm-radio-service_3 actually
AND: if there is the message that service would be downgraded, answer No...
then, manually mount / - o remount,rw and apt install fm-radio-tools only ^^
the PPA has been added and can be used furtheron

Hello @Mardy, I wanted to ask one more question about your radio story. I have already downloaded this zipped radio file from you. Does it matter where you unzip it, or is there a specific folder or directory where it belongs? I have already translated everything else into German. The thing is already clear to me that I have to go into fastboot mode and flash the superimage. Then when the installer runs, don't tick all the boxes and let it run once, do you? I will try while the device is charged again. The problem my device is already fully set up. Oh, I found your FM app in the App Store.

After consultation with Florian, I'd rather wait and see. But if you want you can also test radio apps for FM that I have created. But I won't continue there because I didn't have any success or I don't have the knowledge. I'll just put you all here in the forum. If not, I'll delete the apps again.

@mardy Late to the party, but works like a charm on BQ E5. You might want to edit this article to mention that the BQ kernels are now patched already.

Works also on SHIFT 6mq. But: Can we ship fm-bridge with the service deb? I think that would make things much easier, I forgot about that and it took me now some time to fix it.

@mardy The FM app does not yet run smoothly on the Miatool Xiaomi Redmi Note 9 Pro after some tests. I have noticed the following errors. The Ukw band runs only up to 105100. Everything above does not work. Is the level for the Empfindlichleit too high or not set for Europe? Otherwise, switching mono and stereo from time to time would make sense.

DPITTI

@mardy The Ukw radio for Ubuntu Touch seems to be set too high in sensitivity. There should be an option somewhere where you can change this. So some stations that are below the level do not run at all. I live in the countryside so it would be good to keep the squelch of the app as low as possible. I would recommend the value 10 if the app can do that.
