How can I increase the RF output of my API 6 device?

Is there anything I can do to make my API 6 device transmit with more power?

If you need to increase the RF output of your device, there is a simple trick you can use.

It's necessary to use direct downlink from the Sigfox backend in order to do this - you need to change the value of register 0x55 to 0x70 (default value is 0x72 until now - we've decided to change this from November 2019 and on). This means that the downlink sequence needs to contain this: 0570.

We recommend taking the time to do this only if your use case requires more RF power than usual. Our devices work fine with the old settings as well.
