Yup this was so helpful :) thank you so much xD. I think I might write a comprehensive guide for those trying to do the same thing I did.
sir…thank you so much. I didn’t realize it needed a common ground!!! why is this may I ask? I’ve spend two days looking into this!
This is really odd. Can you confirm my pins?
Connection-wise how I am connecting the sparkfun cc3000 to the LPC1768:
MOSI - > mbed p5
MISO -> mbed p6
SCK -> mbed p7
CS -> mbed p8
INT -> mbed p9
EN -> mbed p10
cc3000 wifi(p9, p10, p8, SPI(p5, p6, p7), "ssid", "password", WPA2, false);
I have a usb powering the mbed and providing serial output. I have a SEPARATE USB female breakout that ONLY provides power to the cc3000 module at 5v 1A. This should be more than enough power for the module. I have switched out my wires multiple times to make sure it isn’t my wires that are causing the disconnect. Since I am getting serial readout, I doubt it’s a connection issue, the problem is though when I turn on debugging only this appears:
cc3000 Hello World demo.
[CC3000 : HCI TX] Command Sent : 0x4000
and it stops. Has this happened to you before? This is so weird because it works perfectly on an arduino uno
Has anyone gotten this to work with the mbed microcontroller? debugging doesnt work for me so I dont know why the module isnt connecting to the Access Point. Im pretty sure my pins are right and I have an external 5v power source supplying power to the module.
No public wish lists :(
