TiWi-SL start up not working

Hello,

MCU -> TIWI-SL

Command : HCI_CMD_SIMPLE_LINK_START

send => 01 00 05 00 00 01 00 40 01 00

receive => 02 00 ff 00 00 00 00 00 00 00 during the transmission

This is exactly what I see from your Saleae Logic file, but I never get a second interrupt back from the TIWI-SL device

If I did, I would go into a read sequence... Does anyone know why?

I never get back Event Opcode = 4000 (HCI_EVNT_UNSOL_BASE)

TiWi-SL start up not working

Hello,

Have you tried more than one module? What host processor are you using?

Can you try calling the wlan_start() function with a parameter of 0x01? That will ignore the patches in the EEPROM and boot the module.

TiWi-SL start up not working

1) I am using STM32F207 as the host processor. Basically, ported over the existing code from the TI processor.

2) I have two modules, the first doesn 't respond at all. However the second module, I can at least see the above data upon send a

// IRQ Line asserted - start the read buffer size command
hci_command_send(HCI_CMND_SIMPLE_LINK_START, ptr, WLAN_SL_INIT_START_PARAMS_LEN);

3) I will try adding the parameter 0x01 into wlan_start(0x01);
