Programmable Bluetooth Transmitter for Extended Range - No Cellphone Required!

Click For Summary
SUMMARY

The discussion centers on building a programmable Bluetooth transmitter capable of broadcasting a continuous signal with a customizable name over a distance of 800 to 1000 meters (2400-3000 feet). The user seeks a solution that connects to power and an antenna, with optional programming via USB, RS232, parallel, or LAN connections. Participants are encouraged to share information on suitable Bluetooth transmitter kits and modules that can meet these specifications.

PREREQUISITES
  • Understanding of Bluetooth technology and its frequency range
  • Familiarity with electronics and circuit design
  • Knowledge of programming interfaces such as USB and RS232
  • Experience with antenna design for extended range applications
NEXT STEPS
  • Research Bluetooth transmitter modules compatible with long-range applications
  • Explore antenna design techniques for enhancing Bluetooth signal range
  • Learn about programming Bluetooth devices using USB and RS232 interfaces
  • Investigate existing projects or kits for programmable Bluetooth transmitters
USEFUL FOR

Electronics enthusiasts, hobbyists in wireless communication, and developers looking to create custom Bluetooth solutions for extended range applications.

---bluetooth transmitter------

hello every one I'm new on this site
and this is the only forum i discovered so far that deals with electronics
i need some help
i'm trying to build a programmable bluetooth transmitter
all i want from that transmitter is this
i need to make a box (not a cellphone)
that connects to power and antenna and a optional connection to a computer (usb, rs232, or parallel, lan, it doesn't matter how) just to program it
and all i want it to do is broadcaster a continues signal on bluetooth frequency so cellphones
can see it, what would be programmable is the name of the signal
and i need it to transmit for about 800 to 1000 miters (2400-3000 feet)
i don't need from the phone to talk back or report back any thing...
just give a signal with a programmable name
if you have any info about any thing that can help me built this

Welcome to the PF. What Bluetooth transmitter kits and modules have you looked at so far?

.
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
