Is this even legal according to the linked ETSI document? ``` The present document applies to RFID interrogators and tags operating together as a system. ``` AFAIK Meshtastic node would...

Leaving this as separate comment for visibility: of you look at section 47b in EU directive table we may be able to use new channels there in 868 band (pending...

Makes sense - but I don't think this should be tied to device role as meshtastic routing and timings have nothing to do with node being fixed or not -...

@rbomze Just FIY - I think NRF52 power consumption (in any mode) can be greatly reduced on many boards by enabling on-chip voltage regulators to work in DC-DC mode instead...

After second thought - maybe it's better way to not use softdevice functions at all (given SD is active only in certain scenarios) and just use raw registers. As SoftDevice...

> During development i learned that direct access to `NRF_POWER->GPREGRET` is definitly unsafe when `sd` is in operation. I encountered various sporadic crashes in development until i learned that. Good...

Yeah, looks good - you can also save flash size by making it a function to be called instead of preprocessor pasting it each time. Also I suppose we will...

@rbomze I did a research about soft device - unfortunately this is hard-baked in Bluetooth library and enabling it externally causes conflicts. So we need to use your idea about...

The only suspicion I have is that calling sd_power* when SD is not enabled may actually crash CPU sometimes without returning an error. This is what happens when you run...

Yeah, sadly Adafruit lib does not try to check if SD is already enabled. Nordic claims that using NVIC_* methods is unsafe if SD is enabled because on soft reboot...
