Wake up time S2LP-DK - - Low Power ?

[Quentin_27]

Hello everyone,

I have a small problem with my shield, the S2LP, when I start a transmission while waiting for an interrupt on my GPIO_0 (interrupt at low state), it sometimes never happens and my timeout is then called after 10 seconds, which is normally good enough to send the whole frame.

I made some modifications and after several searches, I noticed that the problem came in part from the change from SDN to 0 (to wake up the S2LP) :

In the documentation of the spirit it is stated that I normally have to wait 500us for its wake-up, but here as you can see, yet it has 1.5ms! to wake up.

I have some times, problems sending data, but only after I wake-up my board (Nucleo - G070),

after a send fail and if my board don't return in the standby mode I can send, what I want.

Thanks for reading,

Quentin.
