How to increase the range of BLE using software

Hi everyone,

We are in a critical situation. Our devices only can communicate properly within 3 feet. More than that they can't communicate.

我用DA14580 and 5.0.4 SDK

How to increase the range using software settings?can we do withtransmit power & receiver sensitivity?

How to increase the transmit power (more than 0dBm ex +1dBm,+3dBm)

How to change the receiver sensitivity?

As of now, I'm using a ble_peripheral example.

Regards,

Harish

Hi HarishKumar,

Hi HarishKumar,

According to DA14580 datasheet :

  • 0 dBm transmit output power
  • -20 dBm output power in “Near Field Mode”
  • -93 dBm receiver sensitivity

This means that the DA14580 does not have configurable transmit output power.

If you are starting a new design, we would strongly recommend moving to DA14531 or DA14585/586 and our latest SDK6.0.14, as it is much more improved. We have a lot of code examples and improved documentation, and there is also software roadmap support. There is not any software roadmap support for DA14580 product family and SDK5.

Additionally, according to DA14531 datasheet, the DA14531 is capable of Programmable transmit output power from

  • -19.5 dBm to +2.5 dBm
  • -94 dBm receiver sensitivity

Please check out the DA14531:

If you are unable to move into DA14531, you could have an approach like the “Range Extender” reference application design:
