CC2541: How to extend the bluetooth range in CC2541

Hi,

What do you mean by 0dB to 4dB?

What is your application?

If you want to increase the range, you may use CC2592 to boost the Tx power to +22dBm.

But please check your local Regulation on How much Tx power they allow it?

Thanks,

Hi,

Thank you so much for the reply, In cc2541 stack, they have given the option as TX_POWER as  4 DBM how to increase the TX_POWER?

Hi

Thank you so much for the reply, As you said we have increased the transmit power. how to check whether the tx power is increased. can you please guide as

We usually use spectrum analyzer to check this.

Hi 

Thank you so much for the reply, we don't have spectrum analyzer any other option to check the tx power 

Try to use SmartRF Studio to check RSSI.

Hi,

I have one doubt when I read the cc2541 datasheet they have mentioned you can increase up to 0db. but you have said it can increase up to 4db it is possible I am so confused can you please help me

Oops, this is my mistake. CC2541 only support max TX power upto 0 dbm and that's why LL_EXT_MAX_TX_POWER is set to LL_EXT_TX_POWER_0_DBM for CC2541. If you need to increase power, I think adding PA is the only way.
