The Tx power is not correspond to the Uart command

Hi supporter

The result is as below.


Use in ANT_HF port. /media/uploads/williamwu/dsc_0245.jpg By the way , I have tried the sx127x_simple_TX_shield. It can nearly close to the Tx power I set. /media/uploads/williamwu/dsc_0247.jpg

Could it be that 20 dBm boost is not allowed on your frequency plan?

Assume it really can not reach 20 dBm, at least it should nearly fit the result in the third picture. 14dBm is the basic max power all end device acquire.
