Question
How to make s2lp go to TX MODE
Hi
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
