SPWF04 SPI ISSUES

Question asked by Andrew Smit on Jul 12, 2017

We are using the SPWF04 SPI and have the following issues

 

1) No Ack after TCP socket data packet sent:

I can setup a client socket or a server socket and start streaming data but at some point the SPWF04S does not ack and 20 seconds later the module resets. (This 'lockup' is random and can be from a few seconds to 2 minutes)

There is no ack interrupt from the module

We have tried to send differnt sized packets (512 to 3k, with same 'lockup'

 

2) A UDP server socket is opened and the data received via the WIND 55 process. My problem is that 30% of the messages have a faulty byte in the message, i.e. Ç{\"TimeRequest\"}" or "{\"TimeR quest\"}". If the first byte is incorrect it is always a 0x80 ‘Ç ‘ but the byte that is incorrect in the message is always a 0xFF

 

3) How do I reply to a UDP broadcast received on the UDP server socket? If I send a reply via the current socket I don’t receive it on the remote side.
