CC3000 Service Pack 1.7? Where? TxComplete?
this page indicates that there is a service pack 1.7 for the CC3000: http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_for_MCU
Is this yet available for download? If so, where? This is not listed on the CC3000 download page.
The CC3000 download page contains a new CC3000 Host Driver which contains theTxComplete feature. Does this host driver work with the old CC30900 firmware as well?
How can I find out what firmware version my CC3000 has?
Probably you noticed that SP 1.7 is available for download using the patch programmer: http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_for_MCU
The TX complete feature has to have a compatible SP version, probably the old version you have may not support it.
To check the service pack, use this API:
unsigned char nvmem_read_sp_version(unsigned char * patchVer)
thanks for the answer. In the meantime I located the SP 1.7 (8th of August) and I am using it and it works well for me (except for the bugs/observations I reported in other posts).
On the TxComplete feature however I see that this is not working as expected: The workaround without TxComplete suggested by TI is to wait for 1000ms after the last transaction. Now with TxComplete I see that the CC3000 is always waiting for 990-1005ms for me after the last transaction or socket close. This is certainly not working correctly as the last packet for sure is sent only a few (< 10) ms after the last transaction. The goal of TxComplete is to be able to power the CC3000 down fast, not waiting for one second just in case.
To be clear, programmatically it is all working, it is just the timing which is excessive.
Thanks for your feedback, we will verify it.
