Hello I have a confusion when the OOK is enabled in the S2LP chip.
In datasheet section 5.4.2 writes:
The ASK selection depends on power ramping enable.
When OOK is selected, a bit '1' is transmitted with a programmed power, set by register PA_POWER[PA_LEVEL_MAX_INDEX], and a bit '0' is transmitted without output power (PA off) and specified
by the register PA_POWER[0]. In case PA_POWER[0] = 0 then
In case PA_POWER[0] = 0 then the modulation will be OOK, otherwise when PA_POWER[0] is not set to zero the modulation will be ASK.
In datasheet section 5.6.1 writes:
For OOK modulation, the signal is abruptly switched between two levels only: no power and maximum. This mode is obtained setting the PA_RAMP_EN=0.
Statement "In case PA_POWER[0] = 0 then the modulation will be OOK, otherwise when PA_POWER[0] is not set to zero the modulation will be ASK." looks not clear to me. Does it mean even though PA_RAMP_EN is 0, setting PA_POWER[0] to a non-zero value makes it ASK?
