(STM32WL55) What purpose does the "TCXO_WORKAROUND_TIME_MARGIN" delay serve? Can it be removed safely?

[IGold.1]

Sample code includes a 50ms delay "TCXO_WORKAROUND_TIME_MARGIN" in addition to the Radio.GetWakeupTime() when moving from RX to TX. Is this a necessary delay, and if so, why? Higher data-rate LoRa configurations are significantly bottlenecked by this delay.

Hello,

Thank you for your interest

Can you tell me which sample code you are using please ?

What's the specified start-up time of the TCXO's you're using?

>>Is this a necessary delay, and if so, why? 

Time it takes to reach nominal frequency? Dearth of TCXO in market due to fire at AKM? Use of a crystal instead?

>>Higher data-rate LoRa configurations are significantly bottlenecked by this delay.

Yeah, I'd imagine it would, perhaps you can use it selectively, or be aware if the TCXO is up already, or not, and perhaps be more cautious about powering it down, or do so with an actual usage time-out?
