BTH01 BT range

[alexburt]

In there any way to increase range for BTH01 ?
Config show tx power +5 db max. Is it possible to make it +10 db ?
Great project! Thank you!

+5 db = RF_PHY_TX_POWER_EXTRA_MAX

In phy6222 datasheet: TX Power 20 to +10dBm in 3dB steps

RF_PHY_TX_POWER_5DBM = RF_PHY_TX_POWER_EXTRA_MAX
RF_PHY_TX_POWER_0DBM = RF_PHY_TX_POWER_MAX

Take it to the lab and find out.
But that's the maximum number stored in the RF control chip's registers. It can't go any higher.
