Transmit power for aci_hal_set_tx_power_level() for BlueNRG-2

[rdscliff]

What are the power levels for the different settings when calling aci_hal_set_tx_power_level()? All I can find for sure is a max power level of +8 dBm in the datasheet. Other tables I find in the BlueNRG-1_2 DK documentation give conflicting answers and none mention the En_High_Power parameter.

This question was asked before here:

https://community.st.com/s/question/0D50X00009XkfpySAB/which-parameters-are-suitable-for-acihalsettxpowerlevel-with-spbtlerf-

but for a different chip. I'd like to know the answer for BlueNRG-2.

Refer to ACI document, in the BlueNRG GUI package .

Please always set En_High_Power to 1.

And the below table for PA_Level,

0: -14 dBm (High Power)

1: -11 dBm (High Power)

2: -8 dBm (High Power)

3: -5 dBm (High Power)

4: -2 dBm (High Power)

5: 2 dBm (High Power)

6: 4 dBm (High Power)

7: 8 dBm (High Power)

Thanks. How come this information isn't in the BlueNRG-2 datasheet? It seems more like a hardware parameter than a software one.
