I want to expose a minor problem with Oxygenos in bluetooth mode
With the Rom Oxygen in bluetooth mode, the network indicator remains fixed, no signal reception variation. I tested the Rom Pixel experience the signal indicator in bluetooth mode is functional depending on the quality of reception. What to do to correct this problem with Oxygenos.
THANKS
I hope to be
understandable

Hi,
I've been trying to get the FM radio tuner working on my O2 serra which currently has radio version 1.14.25.32 on it. The tuner does work, but the reception is extremely poor and I have tried various different headphones, but none show any improvements. The thing is, I remember it working better than it does now, basically it seems to have degraded, but I don't know at what point, I'm not sure if flashing newer radio versions has affected it at all and therefore I have a couple of questions:
1) Does the radio version actually affect/control the BlueTooth/FM/wifi chip ?
2) Are there any settings or registry entires that can be changed to improve the reception ?
3) Is there a better radio version I should be using ?
When I start the FM radio app. there is a ot of static and the signal strength is full up and I can hear faint radio stations, it won't auto tune in to anything accept my FM transmitter use in the car, even then the signal strength only goes up to the 4th bar.
Sorry for all the basic questions but I've searched and read lots on here but nothing to really answer these question directly.
Regards,
Andy
P.S. I'm actually trying to get TMC working with hypergps, but the reception is making it useless. I even tried it connected to my car antenna with some improvement, but nowhere near enough.
Hi,
I am looking for an API that can read the current ambient rssi with Wifi interface even if there is no AP in the range. Current APIs only returns rssi for an associated AP. How can I add this API in a build? Any direction would be appreciated.
Thanks,
Hossen
What is an ambient RSSI?
If there is no AP in range, whose signal strength do you want to read?
Even if there is no AP, there is some noise signal available (ambient noise). I am working on a project where I need to read the ambient noise value.
Thanks.

Rssi stands for relitive signal strength indication. It is used to measure the received signal strength in a radio receiver.
So what they are looking for is a way to intercept the signal strength that the wifi is receiving from the wireless router and be able to show it on the screen.
Oh and by ambiant noise they are talking about the background noise from other transmitters that might be using the same radio frequencys that the wifi is using.

This might be more appropriate to do research on radio transmitions rather than apps on a phone, for example, set yourself up with radio scanners and antennas that cover the radio frequency's that wifi uses.
P. S. I am a licenced radio ham as well as playing with my phone.

Any moving on?
Hi, guys. I have almost the same problem.
I am working on a project which need to read signal strength in BCM4313.
I try to measure the wireless signal strength ( Adding noise and normal signal up) in the environment constantly. The sample rate is 1000 Hz, for example.
I was working on CC2420 chip-set (which supports 802.15.4). RSSI in CC2420 can does that thing. So I just wonder does RSSI in WiFi has the same functionality.
So I try to dig into the source code of driver , I still can't figure out how to do that.
Thanks for any help.
Best,
Nathan
I found the answer
After reading the source code of the driver for several days, I finally found the method.
There is no general API to do this job. We should dig into driver to obtain ambient rssi. So this is product dependent.
My NIC is Broadcom BCM4313.
I first download the driver from the website of Broadcom. However they don't provide interface to access the hardware. It cost me a lot of time to figure out this.
Then I turn to the open source driver: brcmsmac. It helps.
In the function wlc_phy_noise_sample_request(...) , in /phy/phy_cmn.c folder, I found the example for how to read ambient rssi.

CM13 Bluetooth Issues
I'm running the latest nightly of Cyanogenmod 13 on my HTC One M8 Verizon phone, ran a clean install wiping all partitions and updating to the latest firmware. For some reason my Bluetooth turns off when the screen is locked. Any help?
There has been many issues with Bluetooth. I had constant disconnecting while streaming. The only option is to look at the change log for each nightly & look for Bluetooth fixes.
I'm also running the latest nightlies of CM13 on my verizon m8. I have clean flashed each version (probably 10 days in January). So far I have noticed the following issues:
I see Bluetooth audio stuttering - where the streaming connection to car (ford sync), headset, or speaker (bose) gets quite choppy. 3 seconds of silence, burst of audio, then more silence.
It appears to me to happen when connections change - If i drive away from my house and lose wifi or if I am underground on the subway and gain cell service for a moment, or I drop cell service in an area of sporadic coverage. In every case a reboot solves the problem until the next "connection change". When I am static, or in constant coverage, I have no issues streaming for hours.
Version CM 13.0-20160201-nightly-m8
Baseband 1.12.20.1211
Kernel 3.4.0-gf52bf8c
My OP6 phone status in my cars' displays is erratic. Sometimes it shows the phone signal strength properly, but most of the time it shows no signal (when there is a signal) or nothing at all. This happens in both cars (Nissans). My wife's OP5 shows properly in both cars so the problem is not with the cars. Anyone else with this problem or have a solution?
Every device I've tried with my note 10 has had awful bluetooth crackle unless I really turn down the volume. For some devices (car etc) this is fine, but for something like headphones they become unusable, either being too quiet or sounding awful.
Anyone run into this problem, or have a fix for it? I'm going to try factory resetting the phone and if that doesn't work I will get rid of it and buy something else.
I use my Mi Note 10 with Global rom with my Mondeo mk4 (FL). Full volume, zero crackle/issues.
Check Developer Options, as far as I know you can specify like codecs and whatnot. You might have to set that on your car.
Figured it out. The crackle for me happens when I'm connected to a weak 2.4GHz WiFi access point. Connecting to a 5GHz WiFi or a strong 2.4GHz signal solves the problem completely
It's co channel interference between WiFi and Bluetooth. Hopefully Xiaomi can make some improvements in updates (changing modulation, etc)
