OT Bluetooth Serial adapters

There is a wealth of knowledge and experience within this group. Has
anyone used a Bluetooth serial adapter? I am considering one for my
mobile Kenwood d-710 to utilize an android tablet.

I see there are many implementations but I'm not sure if it is worthy of
consideration.

Thanks for any thoughts.

Some things to consider:

1. From what I can tell, most of these devices are designed to be plugged into a computer.
a. Presumably you’d attach the adapter to the RS232 port of the D710. So the first question is how you’d power it. Power would likely have to come from a USB charger.
b. How do you configure it? Would you attach it to a computer, configure the settings and would the settings be retained by the device (not the computer) when the device is powered down and removed to be reconnected to the D710?

2. The next question is configuring the Android:
a. What software are you intending to use on the Android? Does it use a com port?
b. Is there a way to configure a bluetooth connection as being a com port?
c. Would the software recognize a bluetooth input as a comport?

I don’t have experience with these devices. My suggestion is to first look at the Android and the software you intend to use with the D710 to determine whether it has the capability to recognize a CompPort connection via Bluetooth. Second, when looking at these devices, look at their compatibility in terms of being connected to a non-PC.

Hope this helps,

Re: OT Bluetooth Serial adapters

I have a small Bluetooth adapter that I sometimes use. It's about the size
of a silver dollar, with a short wire with a 3.5mm TRS plug on it. Since I
routinely wear a Bluetooth headset, I can plug the adapter into any 3.5mm
TRS output and pair to the transmitter with my headphones, and don't have
to deal with yet more wires just for my headphones. The only reason I don't
do it more often is that my headphones will only reliably pair with one
device at a time. There IS a way to pair it to two devices, but I've found
it unreliable and don't use it.

It's a help when I have want to connect to a bluetooth speaker, but don't
want to use the AUX cable. If I change devices, I can move the transmitter
to the new device. The only issue is that it's just as easy to use a jumper
cable to the AUX socket on the speaker, and the wire doesn't really cause
that much of a problem.. So it's almost more trouble than it's worth. But
it DOES work, and works just as well on my KX3 as on anything else.

Re: OT Bluetooth Serial adapters

Dang, I misread your post, and didn't see the "serial" part.

I don't use BLUETOOTH serial with my KX3, because there's no way to get the
pairing code. I DO use a 2.4GHz dedicated RF dongle to a wireless keyboard,
that I plug into my PX3. Since it's dedicated, it doesn't need to "pair" to
the device, it's just always connected when active. I tried using wired
keyboards to use the CW/PSK/RTTY feature of the PX3, but I always got stray
RF in the cable, causing unpredictable results, including extra characters
in the keyboard buffer that kept the transmit going past when I'd stopped,
sometimes indefinitely, since the new output stuffed more garbage into the
keyboard buffer. The dedicated wireless doesn't suffer from this, so I can
use the keyboard without problems. (And YES, I did try toroids, chokes,
etc. No help.)

Maybe you can answer my question, then.

A while ago I came into possession of a Dell "wireless" mouse and
keyboard set (Logitec ?) for a desktop computer where I elected to use
wired accessories. The mouse and the dongle are now being used with a
Surface. That leaves the keyboard "stranded". Are "replacement"
dongles available so that keyboard can be used with another computer or
is the keyboard usable only with that dongle?

Re: OT Bluetooth Serial adapters

If it's one of the Logitech "Unifying" dongles, you can get them on Amazon
from various sources:
https://www.amazon.com/logitech-dongle-replacement/s?k=logitech+dongle+replacement
One dongle can support up to 6 Logitech devices on a single computer using
these.

Microsoft dongles, however, are keyed specifically to the keyboard and/or
mouse they were sold with, and you pretty much have to buy a new set if the
dongle goes missing. They can't recode a new dongle.

In reply to this post by kg7vq01

Thanks for the comments.

Yes, I am confused as the the advertised capabilities of the various
models of adapters and tablets. Presently I use a Garmin nuvie 350 but
would like to move to a larger display. What I have works and that
alone may be sufficient.

Some times the mind wanders into the what if.
