STM32WB05KZ POWER ANTENNA modification

[ljm]

Hello 

For the Nucleo STM32WB05KZ board, the transmission power is normally 0 dBm by default (it can go up to 8 dBm).

Is it possible to modify the transmission power according to my needs, for example to 3 or 4 dBm, using STM32CubeProgrammer or another software?

thanks

Hello @ljm 

You can change the TX_Power according to your needs using the 

tBleStatus aci_hal_set_tx_power_level(uint8_t En_High_Power, uint8_t PA_Level);

that you can find here.This function should be called on your code to set the TX power.

This can't be changed throw a SW like CubeProgrammer. It can be changed only throw code.

Best Regards.

Hello 

thank you for replying.

This site is inaccessible "here".

and to do the code with terminal or software can i use ?

thank you

You need to use an IDE to create your code.

PS: link is updated.

Hello

thanks for replying.

in the datasheet de TX and RX specifications are in 0 dB. means that by default pour antenna of board is 0 dBm ? 

since the specifications are in 0 dBm, that means that 0 dBm is the recommanded poewer for antenna ? 

thanks

There is not a default or recommended value of TX Power or RX sensitivity. 0 dBm is the test condition. But for the TX power, it depends on your needs, and it can be 8dBm as mentioned on the DS14591.

Hello,

thank you for replying.

i have new board, how can i know the power of the antenna ?

Also, to modify the the antenna power , i need to do a code with STM32CubeIDE ?

Thanks

[STTwo-32]

Not only CubeIDE, but you can also use any IDE that works with the STM32 (IAR, Keil...). If you want to modify the TX Power, you should do that on the configurations of your application code.

Best Regards.

Hello,

thanks for replying.

actually i have a new STM32WB05KZ board to test, initially what is the power of antenna ( before that i modify it) ? 

thanks

A New NUCLEO-WB05KZ come with the P2P server example code that set the TX Power to 0dBm:
