Hi there,
For a project I try to connect a PIC24FJ256GA704 MCU via SPI1 with the w550io module.
I want the module to be setup as a TCP server. The module can be pinged but not connected via the AX1 loopback test program or similar.
I am using the wizIO library and SPI1 is setup with, Communication width 8Bit, Clock Polarity = Idle:Low, Active:High & Clock Edge: Active to Idle → SPI Mode 0. Input Data is sampled at the Middle.
Can you please check if there is any problem with my code below ?

DEBUGGING:
1.)Serial print via UART
printf(getSn_SR(SOCK_ID_UDP)) returns 3, i can’t find what it means ?
2.) Logic Analyser:
I get signals on MOSI and MISO constantly. There seem to be no errors but i can’t tell if it is working properly. Any advice how I could check from the SPI Signals ?
Do the SPI signals look correct ?
I can ping the module on IP 192.168.1.2, but shouldn’t I be able to ping it on the source IP set in volatile wiz_NetInfo gWIZNETINFO ??
Because I get no ping on 192.168.1.107. I can’t connect on both addresses via the AX1 testing program on PORT 5000.
Am I missing something ?
Any help would be much appreciated!
Best regards
