Title: Is there a table showing Tx power (in dBm) for each setPowerLevel(...) value?
Post by: WhiteHare on March 13, 2017, 07:33:46 PM

I need to figure out which RFM69 library setPowerLevel(...) setting corresponds to at most 11.8dBm (for context: as per the entry in Table 2 in http://www.semtech.com/images/datasheet/fcc_digital_modulation_systems_semtech.pdf )

I'm guessing it would be setPowerLevel(14), or maybe setPowerLevel(13), on an RFM69W?

Thinking out loud, I suppose I could try to narrow down the proper setting based on the current consumed during Tx mode for any particular setting, because the datasheet says the current at +13dBm is 45ma, whereas the current at +10dBm is 33ma.
