Dear Team, @carlrowan
I noticed a serious issue on consumption in transmit with EU868 (not tested other plans). I thought it was on my custom firmware and driver port for mbed-os so I tried with official port STM32WL RAK made for custom firmware but it’s the same thing. So I gave a 3rd try with your official AT Firmware and it’s the same issue.
Let me explain on EU868 transmit is limited to 14dB and all nodes only need approx 40mA max to do that. I understood that RAK3172 can only use RFO High Power path and not RFO_Low Power but since we transmit to 14dB we should not be impacted by this mode right?
But it seems activating RF_HP for 14 dB power has a bad side effect because the module consumption is going to 90mA instead of 40mA, check the capture here.
So does I’m missing something? I would like to know if I’m doing something wrong, if there is a bug or if it’s by design of RFO_HP only?
Because it totally breaks my power budget for my customer.
Not blaming anyone, your competitor (LoRa-E5) as exactly the same issue, trust me I already checked.
Thanks for any help.
