I bought the SFF R410M board to test LTE-M.On the support page https://support.sodaq.com/sodaq-one/sff/ is see that SARA_R4XX_TOGGLE should be HIGH if the R4XX is used. But in the pass through sketch I see the opposite and TOGGLE is LOW. But there only NB-IOT is mentioned and not LTE-M.
So please clarify on the the setting of this pin.
I have updated the support page. TOGGLE LOW for R4.The voltage is depending on the module, not on the radio technology.
