CC3220SF-LAUNCHXL: CC3220 Demo Errors

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH

Thought I was playing it safe - Got the CC3220SF-LAUNCHXL - newest CCS - (I also have IAR, different story there - TI..you need to co-operate more closely with IAR ! your CC3220 projects still don't resolve in IAR!)

Anyway, downloaded all the examples - and about 10 PDF files with (various) methods to get things working. 

The following ALMOST worked: (simplelink_cc32xx_sdk_1_60_00_04)

- Provisioning example(tirtos with CCS)

ALMOST - after Uniflash correct files/certificates (a few PDF's later) gets as far as going around in circles with a poor TI app for IoS (try it - instant brain damage)

- network_terminal(tirtos with CCS)

ALMOST - most commands teasingly work, even 'scan -n 10'  (oh yeah, a few more PDF's to get there-otherwise just errors)

scan shows access points with SSIDS .... try to get past 'Invalid SSID' when trying to connect - I dare ya - be warned, I am well aware of the terminal limitations(no backspace) and can spell etc

So I tried OLD SCHOOL and went for a simple function or 2 myself - got as far as internal errors in some pretty shoddy driver code.

--------------------------------------------------------------------

(Please note - rather simplified version above, I have done this kind of thing a few times before - using Cisco routers? Full of my embedded code, BMW ECU, Ford ECU Indy Car ECU, Mercedes Satnav etc etc)

Hey CC3220 team - go and look at the support code from the MSP430 team !!!!!!! it is Mozart compared to your elevator music !!!!

Can't believe I didn't see it coming, when there are more patches than about 3, it's time to go elsewhere.

No big deal TI - It's only a few 250K or so devices - smart home project - I suppose if I worked for a big appliance company 1 million plus etc I would have gotten better support.

Good thing you aren't the only game in town for 'internet on a chip'

    Hi Richard,

    1. Can you please share what errors you are seeing? If you are using AP mode, have you added the dummy-root-ca-cert and dummy-root-ca-cert-key as documented in the example README? What iOS version are you using?

    2. What AP are you trying to connect to? What command is failing? Both the SSID and password must be in quotation marks.

    3. If you share the errors you are running into, we can help resolve them.

    Best regards,
    Sarah

    Hi Sarah     Hmm.. yes - I actually CAN read - the part about the certificates and the trusted path, hmm wouldn't have though of that - even though I was the programmer who made STUN and TURN stacks for Trinity Convergence in Cambridge, that mean Skype actually works today (Must have gotten lucky huh!).   All I wanted was a good single chip IoT solution, T.I. you led me astray.

    IoS version ? At what level does your 3rd Party App care about IoS version? AP is a Vodafone Connect - new

    Oh and  Usage:   wlanconnect [-help] [-s <"ssid name">] [-t <security type>] [-p <"password">]

      [-ip <static ip>] [-gw <static gw>] [-dns <static dns>] [-ent <"ent_username">]
    -s      SSID
    -t      Type of security (security type = [OPEN, WPA/WPA2, WEP, WPS])
    -p      Password in ascii character (pin in case of WPS)
    -ip     Static IP in '.' format for ipv4 and in ':' for ipv6
    -gw     Static Gateway (relevant in case of using a static IP)
    -dns    Static DNS (relevant in case of using a static IP)
    -ent    Enterprise user name credentials
    You mean ---> "" Those funny things?
    Please Sarah - I can read. I have shared the errors - still no response. Something along the 26 page 150 + step path to 'my first app' has gone slightly wrong.
    Oh please oh please T.I. - PS - My Nordic Semi dev kit is up/running/connected to Freeboard - 23 minutes not bad.
    Hey Sarah - how do you use the CCS IDE to flash the cert files?
    More great questions to come - RCL

    Hi Richard,

    Verifying that certificates have been added is a debugging step that many customers miss at first glance of the README document. You cannot load files to the device's serial flash with the CCS debugger.
    What is the exact issue you are running into with the provisioning example? We verify the iOS version so we can try to replicate your issue.

    What is the format of the SSID name you are using? The default max SSID length defined in wlan.h is 32 characters.

    You mentioned IAR errors and "internal" errors in your first post. What are these errors?

    Best regards,
    Sarah

    Hi,

    You need to use Uniflash software and set your LP into development mode. Please see e2e.ti.com/.../2131099
