I fully understand this board is meant to broadcast an analog or digital reading ,**((so it needs at least the voltage requirement of the sensor )) but if someone just wanted to create a “ beacon“ *with no sensors , could you power this by a single AA or AAA?
So in conclusion I know you listed the power range starting at 3.3v to be able to power the connected sensor, but if the desired use does not have a sensor could you power at a lower voltage i.e. 1.2~3.2v ?
Hello
I am lost in the DF page for this BLE Beacon Pack when I select this product as the sidebar shows a multitude of products and sensors.
Is there a predefined show list of all the sensors shown that can work directly with this Beacon?
Additionally is there a sub-list of any or all sensors that could work with a 1.5V battery or button cell?
JaneYu can you read more than one sensor, if they are all i2c?
JaneYu The current version does not support connecting I2C sensors, please pay attention to our new products, we will launch a BLE Beacon that supports I2C sensors, which can read multiple I2C sensors
Hello, we have released BLE Beacon with I2C support. you can check this link:

Not pre-programmed, all the content of the advertising can be customized through a visualization software, please refer to the product wiki.
JaneYu Sure, Gravity: BLE beacons support custom broadcast packet formats, so you can adapt the data format to the AOA receiver's positioning algorithm. This is a commendable attempt, please contact us if you have any additional questions.
JaneYu Can I use the device to read sensor values, store them (I would need around 512kb), and then make the data avilable to be sent?
JaneYu Hi! The sensor data cannot be stored down in the beacon, perhaps you can broadcast the data and store it on the receiving end.
Hello DFROBOT friends!!
You have great step by step screen shots and directions on how to get this working.
Do you have any idea what the max Tx (dBm) setting is for custom with your Gravity BLE board ?
Your getting starter documents have a suggested setting of “5” , and in some of the inplay software documents they have “8” for the Tx setting
Just trying to understand the possible parameters, I plan do a “range test” and want the best performance
Thanks and Happy New Year 🎊
