I’m thrilled to share our latest project on Kickstarter – MultiNav Pro+ BLE, a powerful Bluetooth module designed to redefine what's possible in wireless communication for IoT and embedded systems!
Unmatched Range: With a Bluetooth range of over 5KM with a smartphone and up to 50KM when communicating between two modules, this is the ideal solution for projects that need long-distance connectivity. Imagine the possibilities for remote monitoring, outdoor robotics, drones, and more!
High Data Rate: Supporting up to 2 Mbps, MultiNav Pro+ BLE allows you to transmit data efficiently, which is crucial for real-time applications and smooth communication in high-demand environments.
Advanced Features & Connectivity:
Dual-core STM32WB07CCV6: Combining BLE with ARM Cortex-M0, ensuring robust performance and flexibility.
Powerful RF Front-End: Users can adjust transmission power and receive amplifier gain, making it adaptable to a wide range of environments.
Multiple Interfaces: Compatible with MultiNav Pro+ GNSS module for navigation, MultiNav Pro+ Sensors module for environmental monitoring, and capable of interfacing with motors and battery management systems.
Why Back the Project?
We’re launching this module exclusively on Kickstarter with a limited-time price, giving you early access to this breakthrough module and helping us make it a reality. Plus, we’re offering special rewards and exclusive pricing for backers – this is your chance to be among the first to integrate MultiNav Pro+ BLE into your projects.
Imagine the new possibilities with MultiNav Pro+ BLE – for both hobby and professional projects. If you’re passionate about IoT, remote sensing, or simply want to take your Arduino projects to new heights, this module is designed for you!
Check out our Kickstarter page and support the project! Let's bring next-level Bluetooth connectivity to the maker community.
Thanks for your support, and feel free to ask any questions about MultiNav Pro+ BLE! Let's discuss how this module could change the way we build and innovate.
The receiver sensitivity is quoted at -104dBm for 2mbps, so adding a 12dB LNA at the RX end and 20dBm TX power would get you close to the path loss @50km of -134dBm.
A 2.4Ghz LoRa module has a much lower maximum data rate of 'only' 0.2mbps where the quoted gain is -99dBm. So this Bluetooth module appears to have a significantly higher receiver gain than a LoRa module and is also capable of 10 times the data rate, 2mbps.
@srnet yes it was a challenge to achieve it!
if you refer to STM32WB07CCV6 datasheet from STMicroelectronics, kindly find it attached Datasheet.pdf (4.3 MB)
you will find that the transmitted power and receiver sensitivity is configurable, -104dBm sensitivity (long range) comes @125Kbps bandwidth where thermal noise floor is around -123dBm @25 degree C, thinking from the transmitter side where you have signal power of 20dBm (there is still antenna gain of 5.1dBm but let's not count it to be FCC compliant) so the signal that arrives at the receiver antenna after subtracting 134.2dBm path losses will be - 114.2dBm which is above the noise floor, then we have the antenna at the receiver, LNA (low noise amplifier).
Having BLE chip with configurable transmitted power and receiver sensitivity in addition to the tunable RF front-end makes the Module a unique RF experience where you simply change some parameters and experience the performance in real time!
The front-end allows maximum of 22.5dBm at the antenna connector. In our ready examples that will be published on the website we configure the chip power + amplifier gain to be in total 15dBm then there is 5dB by the antenna (to be compliant with FCC). The software will be provided as an open source library so users can tune, learn, and reconfigure it.
