CC2340R5: host test application example range

Hi !

I don't exactly understand what you are asking for. Are you receiving the data at close range but not at far range ?

When you say that you are not getting scan response, are you talking about btool scanning for devices or BLE advertisement scan responses ?

Kind regards,
Lea

yes, I am receiving data at close range but not at far

yes, I am using btool is scanning for device

Hi !

If you wish to increase the distance at which you can scan for devices, what you can do is increase the TX power of your advertising device.
To do that, you can read the following chapter in the user guide : Changing txPower for an advertising set.

Kind regards,

I know it I am getting my adv and scan response data at my phone from approx 50 meter but not in the launchpad in which i uploded the host test code and and using btool to get data 

Hi !

The range for reception can be affected by many thing. As previously stated, the tx power of the emitter plays a huge factor. However, more factors come into play, such as the environment, the protocol used, and the antenna gain. It's possible that the antenna gain of the phone is much higher than the antenna gain of the launchpad (See here for the characterisation of the inverted F antenna for the CC2340R5).

The solutions to increase the range of advertisements are the following :
- Increase the TX power of the peripheral device
- Use LE Coded PHY instead of the regular 1M PHY
- Reduce the number of obstacles / Have line of sight between the two devices
- Reduce the amount of radio noise in the environment

Kind regards,
Lea
