Hello,
I am currently testing Bluetooth LE communication between two STM32WB5MM-DK boards. For the test, I am using
the data_throughput example, which I've adapted from the P-NUCLEO-WB55 software package.
According to the official datasheet for the STM32WB5MMG module, the "Features" section mentions a
communication range of "up to 75 meters."
However, in my real-world tests, I am only achieving a stable connection range of about 10 meters. My test
conditions are as follows:
* TX Power: +6 dBm (the maximum setting)
* TX PHY: 1 Mbps
This significant difference between the datasheet specification and my results leads to two main questions:
1. Are there any recommended methods to increase the communication range using this same hardware setup
(STM32WB5MM-DK)? For example, are there specific software configurations or best practices I might be missing?
2. Under what specific test conditions was the "up to 75 meters" range validated by ST? Understanding the test
environment (e.g., open-air, line-of-sight, PHY used) would be very helpful for me to manage my expectations
and design accordingly.
Any advice or insights on this matter would be greatly appreciated.
Thank you.
