Hi! I got strange problem with RFM69H radios. I have : 2x Arduino Pro mini dual power 5V/3.3V clones (power option set on 3.3V) 2x Hoperf RFM69H models (max power 100mW at 130mA) 2x external 3.3V power supplies
Based on this tutorial from Adafruit, I manage them to send/receive data.
Problem - in TX mode maximum power consumption is only 20mA (should be ~130mA), so I'm not using max potential of these modules (anyway - range is better than NRF24l01+).
Have tried both major libraries - RadioHead and LowPowerLabs - same result on both. Have tried modules from different vendors.
Does anyone who have these high power modules managed to get max power from them on standard Arduino(except original Moteino)?
My guess is problem with dual voltage arduino, so I already ordered pure 3.3V versions.
