CC3100 don't ack sl_WlanDisconnect command

Other Parts Discussed in Thread: CC3100MOD, CC3100

Hi All,

we found another big problem with CC3100MOD (SDK 1.2, ServicePack_1.0.1.6-2.6.0.5) The module don't ack sl_WlanDisconnect command

we inspect serial line an we get the following transactions

HOST: FFEEDDBB21433412818C00

pause > 60ms

CC3100: BADCCDAB6300040038000000

in the wiki I red that a command sould be always acknowledged, so I don't understand this behaviour of the CC3100MOD

Any Idea ?

Hi All,

Further investigations suggest that the problem is due to sl_WlanProfileDel(0xFF). This call is successfull, but if we send a disconnect command after this the module don't acknolege command, but is still alive: send a DeviceAsyncDummy

This is some test about WlanDisconnect,

		osi_Sleep(10);
		sl_WlanPolicySet(SL_POLICY_CONNECTION, SL_CONNECTION_POLICY(0, 0, 0, 0, 0), NULL, 0);
		if (retVal < 0) {
			break;
		}

	    retVal = sl_WlanDisconnect();

After sending sl_WlanPolicySet, CC3100 rise IRQ line, Host driver send CSYNC word, the module deassert irq line, after that HOST software send spi clock forever
waiting device To Host sync word.

In my opinion any comand, else if in grong sequence should return an error code, not hang software
