How can i control a rssi of the BL600 series ?

[Takayuki Yoshinaka]

Hi,

I am developing ble apps with the BL600.
I am coding a source file with the keil IDE. And this source is deployed to the nRF51 DK board through the nRFgo Studio.

Now, i am considering that i want to adjust the strength of rssi value.

First, i tried to use the 'sd_ble_gap_tx_power_set' method for it.
An argument of this method was 4.
And i built it and deployed it to the BL600.

But, a rssi did not become a stronger.
A rssi had shown about -80 dBm.

Next, i deployed the same code to the nRF51 DK board directly.
Then, i checked a rssi value, it had shown about -35 dBm.

My questions:

• Can the 'sd_ble_gap_tx_power_set' method control a strenght of rssi on the BL600 ?
• Is there other methods which be able to control it ?

I thank you for reading it through.
