'[AD] Bluetooth 'industrial' serial module'
2010\01\28@175050 by Peter

In line with the discussion about interfacing Bluetooth devices to a PC, this is
a serial to bluetooth module. The device appears as normal serial device on the
PC side, once recognized and after handshaking completes with the Bluetooth
stack. I post this here since it may be of interest to many here. I have no
affiliation with the company or the product:

what's the temp range and current consumption on this module?
Is it a class 1 device? If not, why it sells in a class 1 device price?

I have no idea. There is a link to a datasheet on that page. Also they say it is
a class 2 device. What is the connection between the price and the class?!

I got a few quote from different BlueTooth module vendors, class 1 are in the US$20 range, class 2 are in the US$7~10 range.

I read the datasheet on the web you posted, didn't find class information.

I have not seen such low prices as you mention ( $7 to $20 ) for  
Serial BlueTooth modules.
Would you mind telling me where you got these quotes and for what  
quantity ?

Class              Maximum Permitted Power       mW (dBm)          
Range    (approximate)
Class 1                 100 mW                                      
(20 dBm)                   ~100 metres
Class 2                   2.5 mW                                    (4  
dBm)                         ~10 metres
Class 3                     1 mW                                        
(0 dBm)                         ~1 metres

Hi, Gus,
There are a few BT vendor (USA and oversea) is talking with us to let us carry their BT modules on our web site and online store.

Class 1 is on the range of US$2x due to the fact it outputs more power and uses a ceramic antenna, a metal shield is included for EMI performance. I can get this price in low quantity.

Class 2 is another story, it uses PCB antenna, no metal shield, 1K(minimum order) price is about US$7.x, sample price is around US$10.

Both type of modules include BT SPP (Serial port protocol) which make them good turn-key solution as serial cable replacements.

Due to the fact this is a low-profit margin market, we may not jump in eventually. But we will use some in our own products & a lot in our OEM designs too.

Contact us off-line if you are interested.

The webpage contains the line: '● Emission power:  â‰¤4dBm, Class 2'. Why was this
hard to find?

Not only that, the temp info, current info are now  available.
I didn't find those info on the first run, did you work for this company?

There is a limit to how far this questioning can go. You can find my exact
position towards the products and the company in my first posting, Mr. Funny.
The class information pertaining to the product being discussed was there the
first time too, as I saved the page the first time. I hope that you will find
the exact information with regards to my position towards the company and the
product in my first posting upon a second reading thereof, although I did not
modify the posting. Thank you for this dialgoue, Mr. Funny, it will be
remembered. It has been a pleasure to get to know you better, Mr. Funny.

FCC certified?

I didn't see the FCC mark in the documents, but it claims "Bluetooth Qualified product". I can check with the supplier.
