S2LP maximum power transmit problem

hi,

I am trying to transmit at maximum power using S2-LP. I set the configuration registers using S2-LP DK Application tool version 1.3.4. I set output power as 14dBm, check the MAX power box, choose HPM mode (in PM mode section), set 1600mV SMPS voltage level. According to datasheet at maximum tx power S2LP consumes about 20mA. However, I did never measure more than 12mA (including STM32L051 uc consumption).

After that I opened an example project from CubeMX, project name is "S2868A1_P2P". I also tested with same nucleo board (L053) and reached about 30mA at maximum power. However using the same configuration registers I could not able to reach maximum power.

Is there any configuration that I missed?

best regards,

Can İNEL
