Thanks for your reply.

So basically, 2 bluebee will be connected automatically when both of them are powered on if the master bluebee not yet connect to other devices previously? So , i dont need to manually connect them right?

Does that mean the API is working and able to display value when 2 bluebee are connected( e.g getRSSI function) and not like previously i connect smartphone to bluebee 4.0 ( which is not working to get RSSI value using API) ?

Hi,

If the master BlueBee doesn't connect to any device before, yes it will search for nearest BlueBee 4.0 slave to connect if it is in Master mode. For next powerup, you don't need to connect them manually, they will do it by themselves!

Yes, getRSSI function will work in this case.

Hi,

thank you for reply !

One last question.

Is it possible to connect the module with CR2032 battery without xbee shield or arduino microcontroller? Is like i just need to power on the module to allow the bluetooth signal transmission without pairing with other devices.
Because i have been reading and doing research about BLE module, and seem most of them are using CR 2032 battery to power up it which can last longer.

Hi,

Without Xbee shield, yes it is possible. But without microcontroller, no. BlueBee 4.0 for now is the module that acts as the medium to transfer data from one device to another. A microcontroller is a must to send data or process incoming data. However, if you are aiming for power saving, you can try to work on microcontroller instead. Like to put microcontroller in sleep mode, etc. You can search for more info online.

Well for this one, I don't know which power source you are compared to CR 2032. To power the system longer, of course constant power supply like power adapter is always the best choice.

Thank you.

How bout implementing additional antenna on the bluebee 4.0 module? is it possible?

And I have been connecting the bluebee 4.0 module and test the distance until it is disconnected. And distance is not as accurate as it is mentioned in the website. It disconnected after 10 meters with obstacles. May I know the reason behind this?

Hi, you can check out this article.

Thank you Apis.

I think is my smartphone bluetooth range which cannot support up to 30meters at least.

If bluebee 4.0 pairing with bluebee4.0 , i think it is possible to connect up to 30 meters at least.

Hi,

May I ask if i connect bluebee 4.0 to bluebee 4.0 module that connected with arduino uno microcontroller,am I able to display the data on my laptop on the arduino serial monitor ( e.g RSSI value between the 2 modules) ?

yes

Hi,

May i ask the RSSI value is in Dbm or Db unit?
