CC3220MOD: Modify Default AP SSID in UCF File

Bryan Radke

Part Number: CC3220MOD
Other Parts Discussed in Thread: UNIFLASH, CC3200,

We are using the *.ucf file format for our initial programming of our device. We are using the embedded programming tool to flash the device. We are looking for a way to make the SSID on each unit unique, but we do not want to connect to the device to change the SSID. Is there a way to modify the *.ucf file so that the SSID can be different for each program? Is there anything else we could do?

    Hi,

    I think easiest way is add this functionality into your code. You can detect first boot and set SSID to unique according MOD MAC address.

    We are looking for a way to use our manufactured boards serial number in the SSID string. We need a way for our customers to know which unit they're initially interfacing with. If the MAC address is used, someone still needs to connect into the device to make note of the MAC address. We are trying to decrease manufacturing time. Having someone connect to the device will take too much time.

    Hi,

    Yes, I understand but I think that is no official way how edit gang image for embedded programming. And if I am not wrong required feature is not available via Uniflash 4 CLI interface. For example with previous CC3200 and Uniflash 3.4 this was possible.

    But I don't think that connection with device and writing some information will dramatical slow your production. You still need to done RF test with your produced devices, which take more time. Or you don't want to do RF tests at each produced device? This could be very risky strategy. Only with CC3220MODA this can be acceptable.
