Bluetooth components selection? Any already made devices?

In summary, you should find a Bluetooth serial modem, preferably one that is low in price and has a good amount of reviews.

Bluetooth components selection? Any "already made" devices?

Hi all, this is what I want to get done: a device1 reads data from sensor using a parallel port, then send it to a device2.

Here is what I can think of about device1, it should be a very small 8bit smp MCU controlling a com device, preferably a bluetooth module, since going into the detail of bluetooth would be a house of pain.

So for device1, it should work like this: sensor sends 8bit parallel data to the MCU, then the MCU activates the bluetooth module, pass it with the data, and make it send the data.

My problem is: I do not know what product to choose, I mean there are products out there available that implement my goal, but I do not know who manufacture them, and which one has the best cost/benefit ratio. Do I really have to buy a bluetooth module, and a MCU miniboard and put the two together? Somebody must have done that job long time ago?



Any suggestion would be appreciated! Thanks!

It sounds as if you're looking for something like a Bluetooth serial modem, which acts just like a serial cable between the host and target:

I've used ones from WCSC and IOGear--they both seem to do a reasonable job (although the IOGear one isn't sold in pairs):

They're mostly in the price range of around $200 a pair.

200? That's way too expensive!

Well, you did ask for ready-made!

If cost is a major objective, I'd just go with a wired connection. Most of the wireless schemes (RF serial modems, ZigBee, Wi-Fi, etc.) I'm familiar with are about in the same ball-park price-wise for low quantities.

I see... guess I'll have to find another way around.

Actually, this one's only about $90 for a pair:

If that's still too rich for your blood, you should reevaluate whether or not wireless transmission is actually a necessity.
Thanks MATLABdude, I've already found something that might come in handy, thanks 800 tons for your help! :)

1. What are the key factors to consider when selecting Bluetooth components?

When selecting Bluetooth components, there are several key factors to consider, including compatibility with your device, power consumption, range, data transfer speed, and cost. It is important to carefully evaluate these factors to ensure that the components you choose will meet the requirements of your specific project.

2. Can I use any Bluetooth components for my device?

No, not all Bluetooth components are compatible with every device. It is important to select components that are specifically designed and certified for use with your device. This will ensure proper functionality and reduce the risk of compatibility issues.

3. How do I determine the appropriate range for my Bluetooth device?

The range of a Bluetooth device is determined by several factors, including the power output of the transmitter, the antenna design, and any potential obstacles or interference in the environment. It is important to carefully consider these factors when selecting Bluetooth components to ensure that your device will have the desired range for its intended use.

4. Are there any pre-made Bluetooth devices available for purchase?

Yes, there are many pre-made Bluetooth devices available for purchase, such as headphones, speakers, and smart home devices. These devices typically come with all the necessary Bluetooth components already integrated, making it easy for consumers to use them right out of the box.

5. Can I customize pre-made Bluetooth devices to fit my specific needs?

Yes, many pre-made Bluetooth devices offer customization options, such as the ability to change settings or add new features through a companion app. However, the customization options may be limited, and it is important to carefully research and read reviews to determine if a pre-made device will meet your specific needs.
