Hello,

actually, i'm using the bluetooth module BlueNRG-M2 , and i want to know the communication distance in meter please and the length of the antenna .

Thank you

Again, that's really not something that can be specified for a module alone - it depends very much on the rest of the system.

This is why manufacturers do evaluation modules - so that you can try it out in your particular system & conditions.

The supported baud rates will be specified in the datasheet.

There are 2 versions:

  1. On-board chip antenna (BLUENRG-M2SA);
  2. PCB antenna (BLUENRG-M2SP).

So which one do you have?

Dimensions are in the datasheet.

Achievable range will depend very much on the application.

hello @Andrew Neil 

thanks for replying, i have both of them : 

  1. On-board chip antenna (BLUENRG-M2SA);
  2. PCB antenna (BLUENRG-M2SP)

Also if it's possible to  recommand me other bluetooth BLE reference better.

Thank you very much

What kind of "reference" ?

In what way(s) "better" - and "better" than what? 

Have you looked at the resources on the Product Page?

i want a BLE bluetooth module with range between 10 m and 30 m and, above all, is not sensitive to interferences. (also like option if it can i use it with arduino ).

Thanks

In general, BLE should be able to achieve 10-30m unobstructed - but obstructions (your product casing, people, walls, etc) will reduce that.

That would fall within the BLE specs.

Anything can be used with Arduino - it's just (sic) a matter of having the right code ...

hello @Andrew Neil 

Thanks for replying.

Means that the distance of communication using the 

  1. On-board chip antenna (BLUENRG-M2SA);
  2. PCB antenna (BLUENRG-M2SP)  

is + 10m ? 

also please i want to be sure about the baud rate using this module ( baud rate of my application between 9600 and 115200) and how many bytes / S 

thank you very much
