TCPServer / TCPClient still unreliable?

Troubleshooting
1

Hi, is there anyone who got a (local) TCPServer to work reliably on the SparkCore?

Here’s what I tried:

  • Reading tons of threads on the topic
  • Running the TCPServer example from docs
  • Running countless “working” 3rd party examples
  • Flashing a deep update with particle flash --usb deep_update_2014_06
  • Updating CC3000 with particle flash --usb cc3000
  • Using different system modes

The result is always the same:

  • Requests to the TCPServer work sometimes, are often slow and after about 10 requests often hang
  • After a while (10s of minutes) the device becomes unreachable, even if no requests have been made
  • Using curl works slightly better than a browser (maybe related to size of request headers or parallel requests)

Any comments, working code, ideas or up to date info?

Kind regards,
Thomas

Could you try flashing the latest Service Pack from https://github.com/spark/cc3000-patch-programmer/tree/ti-patch-1.14

There were a number of fixes and stability improvements there.

Thanks for the quick reply.

After flashing the cc3000 with dfu-util -d 1d50:607f -a 0 -s 0x08005000:leave -D cc3000-patch-programmer.bin (as included with https://github.com/spark/cc3000-patch-programmer/tree/ti-patch-1.14, without calling make) my code now runs through 99+ requests. Seems to be an improvement at least.

Kind regards,
Thomas
