CC3000 SPI does not transmit data any more after recvfrom

F.S. (AIT Austrian Institute of Technology)

Hello,

I am trying to realize a simple udp connection between my cc3000 and my laptop. I neared now the problem to the wlan.c file. Every time I transmit data from my laptop to the module the code stuck in the if (tSLInformation.usEventOrDataReceived != 0) from the event_handler.c file. This variable is never set to 1 by the void SpiReceiveHandler(void *pvBuffer) function fom wlan.c after transmitting the data. On the other hand, I can send Data without any problems to my laptop…

I am using my oscilloscope also and it clearly shows that the /SPI_IRQ Pin is after sending the data permanently low. My Firmware is the V1.14 and I am using the CC3000 with the MSP430-EXP4618/F2013.

Does anyone know why this is happening?

Hi,

1. Can you please confirm that parameters like IP address and port are correctly provided in the UDP client?
2. "SPI_IRQ Pin is after sending the data permanently low". What are you sending here?
3. Are you using the service pack version 1.32?

Regards,
Raghavendra

Hi Raghavendra,

thank you for your answer. I am very very sorry for my late answer. I was impeded though work and could not answer for quite some time. However, I am still working on the CC3000 module. I hope it is not to disrespectful if I ask you again for your help. Yes, my service pack verrsion is 1.32. Ok, but if it is permanently low after sending, why the tSLInformation.usEventOrDataReceived != 0 is not set true by void SpiReceiveHandler(void *pvBuffer)?? The endless loop stucks because of this variable.

regards,
F.S.

I am sending just an 'a' to the designated port. The module responds by pulling the IRQ pin perminantley to low but the correct length measuured by recvfrom is never printed. also debug messages after recvfrom are not printde. it simply stucks and nothing happens after the module receives something, regardless what.
