blecm_setTxPowerInADV not working in SDK 2.1.1

Hi Boont,

Thank you.

I've check the article last week, but the Power_Table shows it can go to -25 dBm

That's why I am asking now.

In your words, the Tx power just can be set to -6dBm for minimum value?

Like below?

blecm_setTxPowerInADV(-6);

Ok,

I will check the real Tx power with RF engineers.

Thanks.

In the test field we may have 2 or more host device scanning for the devices.

When first time bonding, we will put the device and the host as near as it can, and we do not want some other hosts to scan the device and "rob" the bonding and connection. That's why we need an lower Tx power advertisement like a "whisper".

Hi BoonT_56,

We have test that the power, seems the blecm_setTxPowerInADV() function works.

The measurement shown the power is about 0dBm when we set blecm_setTxPowerInADV(4), and the measurement shown -9dBm when we set blecm_setTxPowerInADV(-6).

Here are 2 more issue:

1. The adv period=100ms It hard to get the 3 pulses in our measurement screen, should we have to change some option in BCM20737 for improving this problem?

2. As I know, the advertising channels are placed at 2402MHz, 2426MHz and 2480MHz. Below is one of our measurement, Is seems the channel 38 (The middle one) is placed in 2.428GHz. Is there any problem about the RF? (Please note that the 3 pulses didn't exist together, we have wait about 10 seconds to get this, why?)

Hi BoonT_56,

I think I have verified the function blecm_setTxPowerInADV() is work. This topic can be closed now. I will continue test with the advertising signal, and will create another topic to talk about the signal issue.

Thanks.
