Bluetooth 4.0 w/ multiple devices


Recommended Posts

Not sure if this is the right place for this kind of question, but I thought I'd give it a shot.


I am going to buy a new Android smartphone soon and it will have bluetooth 4.0. I mainly use bluetooth to connect to my Toyota in-dash enTune system, so it is a voice and data bluetooth connection.


I also have an interest in using the new FitBit personal exercise tracking device. Their new model is bluetooth 4.0 so instead of having to connect it to your computer to download the fitness data, it communicates with an app on your Smartphone continuously using the new bluetooth 4.0 low power standard.


Here is my question....does bluetooth 4.0 allow multiple devices to communicate with the phone? In other words, while I don't really care if my FitBit is actually communicating with my phone while I am driving my car, I don't want to have to manually connect or disconnect bluetooth profiles multiple times per day when I get in my car.


Likewise, if I am walking around the office and the my Fitbit is communicating with my phone, when I get in my car I want my Toyota enTune in-dash to work without turning off my Fitbit connection and connecting to my car every time.


Does anyone know? Will this all happen fluidly and without my intervention? Thanks!

Sure, but as I understand how 4.0 low power works, devices are basically "always" connected. They may exchange data at a ping rate of every 10 seconds or so continuously. IF that is true, then how does that work with multiple devices because you no longer have a situation where a device is on/off or in range and out of range. I would have a fitness device on my belt 12 hours a day constantly talking to my phone. So what happens when I get in the car and want to stream Pandora?

My use case includes a Wahoo Fitness Blue HR HRM, which is a BT 4.0 low-power device. I can add to that BT headphones, or even hop in the car and use the car's BT stereo and handsfree systems and the Wahoo keeps connected. Maybe I misunderstand your question?

Nope. You've got it. Perfect. I just needed to hear from someone that also has the same use case. I wasn't sure how the constantly connected fitness device would impact things. Thanks.

    • Yes, that is where the site used to be. All the antennas were removed. I hope they add a new site soon. Have any permits been submitted for a new site?
    • Looks like there's a slightly taller building going up next door to where the decommissioned site used to be. Taking a look at StreetView, T-Mobile likely decommissioned the site because the east facing sector would blocked by the new building. If I had to guess, T-Mobile has already agreed to move to the roof of the new building and is just waiting for it to be completed to install the site there. What they should've done is just rearrange the sectors in the meantime but it seems like T-Mobile just bit the bullet and decommed the tower in the short term. — — — — — A permit was issued for a Sprint conversion at 150 Prospect Park West, finally filling in what is T-Mobile's largest coverage gap in Park Slope. Verizon is collocated on that building and AT&T has placed small cells along Prospect Park West to fill in coverage there while T-Mobile struggled using two sites, one at Grand Army Plaza at the far north and another at Bartel Pritchard Square to the far south.  
    • Yep, you can see the site was taken down between Aug 2022 and Apr 2023.
    • Verizon site at Woodbury Commons finally got C-band. I'm seeing upwards of 600Mbps there, a massive improvement over the <1Mbps I used to see. LTE is now at 10-20Mbps which is significantly better than before where speed tests would often fail. My only complaint is that C-band is super inconsistent. Not sure if it's a software issue but sometimes I'm connected to it and get the 600Mbps speeds previously mentioned and other times I connect and only see 15Mbps. Seems like whatever load balancing the network is trying to do is still shoving a ton of people to LTE, even in conditions where I have a strong C-band signal.  — — — — — You're absolutely right. The site on top of Bais Sarah Hall at 6101 16th Ave got decommissioned. Sad that they haven't installed a new site to fill in that coverage gap.  — — — — — In other news a carrier reached out to the board of my grandmother's building in Brooklyn about installing antennas on top of it so she called me today because she knows I map cell towers and she said a lot of people in her building, especially the folks on the upper floors, are worried about the health effects lol. I asked her if she knew what carrier it would be but she said she doesn't know. A quick glance at Cellmapper tells me it's either Dish or AT&T since Verizon and T-Mobile both have sites within a two block radius of her building but AT&T barely builds new sites so I'm leaning Dish. They're asking for a 25-year lease with an option to renegotiate the lease after 10-years. The board of her co-op said that if they do it, maintenance fees will go down since they'll be offset by the rent that the carrier would be paying them. She said she already voted in favor of it but she thinks that a lot of the older people in her building are against it.
    • Galaxy S7 FE most certainly doesn't have the same level of NR CA (if at all), it also looks like it doesn't have SA NR, so it's is inherently going to be much slower since most of the spectrum is now focused on NR rather than LTE. It's likely the same generation radio as the S21 (or maybe S20). Having trouble finding which it would be.
