Currently I am tuning the advertisement Tx power by blecm_setTxPowerInADV()
originally I used
to get the max TX power, I roughly measured the RSSI by iSO app, it shows -36~-40dBm
When I change to
It still shows -36~-40
And then I try
The measurement is still the same.
I also found the .tx_power_level in BLE_PROFILE_CFG structure is "UINT8" type, it will have some problem if we set the negative number in the parameter. Is there something wrong with the TX power setting functions?
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.
