How to make s2lp go to TX MODE

0690X00000AALATQA5.pngHi

I tried to develop my own code for s2lp on NUCLEO-L476RG

my setup include:

NUCLEO-L476RG+s2lp FKI433v2 on top(RX working fine)

NUCLEO-L476RG+s2lp FKI433v2 on top(TX cant go to TX mode)

NUCLEO-L053R8+s2lp FKI433v2 on top(as a test for both RX and TX)

I was able to receive messages with the my code on the RX side the message was from the L053R to my L47RG

However when I Tried to send From TX L476RG it Wouldn't send Nor Got to TX mode

I know this because i saw the S2lp status Bit after I sent the TX Command it didn't go to TX MODE but Went to Ready only

The status Bits were(52  1)

I am using kiel V5 and did initialize with Cube MX

hi, did you got it working?

am facing similar issue with s2lp transmitter, considering am fairly new to rf design, so am more of in learning by doing mode. Sigfox is pretty far for me as of now.

If you have time would like to know how and what steps did you follow to set s2lp in Tx mode as well as Rx. I was actually trying to generate CW first but it did,nt worked.

SPI is working fine and device is indeed going into ready/standby and sleep state, tried to go on with tx and lock commands and device state is as per the command issued, but no response on tx and rx side am not sure whether it is due to register configuration or what.

so any help would be good enough apart from "good-luck"

Hi

I got it fixed the main thing was that i changed the

PCKTCTRL3 RX mode direct through FIFO

and

PCKTCTRL1 TX mode direct through FIFO

then i was able to to change it to TX mode

I was able to send and receive with s2lp but i couldn't do the RCS so i disabled it
