Part Number: BOOSTXL-CC3135
Other Parts Discussed in Thread: CC3135, UNIFLASH, CC3100SDK, CC3100, CC3120
Hello. I am trying to use CC3135 using STM32f103 (Nucleo board) by porting SimpleLink CC3100SDK 1.3.0. I have uploaded the service pack 4.1.0.28_3.1.0.5_3.1.0.17 (most recent version) through Uniflash.
During porting the SDK, I replaced the SPI related function (spi_open, read, write, close) based on the pre-defined function like MX_SPI_Init(), MX_GPIO_Init() through CUBEmx. Furthermore, I have added needed event handlers and functions to deal with the interrupt signal from the IRQ pin from the CC3135.
Problems are the return value of sl_Start is always 1 (ROLE_UNKNOWN) and the program get stuck at the 'SL_DRV_SYNC_OBJ_WAIT_TIMEOUT' when I call sl_Stop(). In the case of sl_Stop, if I call the sl_Stop(0), then it does not get stuck.
The wired point is that, if I set the AP mode to the CC3135 using sl_WlanSetModeI(ROLE_AP), zero is returned and I can search the AP in my cell phone or laptop. This AP can be appeared and disappeared on my cell phone when I call sl_start and sl_Stop(0), repeatedly.
Also, if I called the sl_NetCFgGet to get the MAC address of the CC3135, it returns 0 which shows there is no problem during the command. However, the returned MAC address (macAddressVal[]) were 0x3, 0x34, 0x0, 0x6, 0x0, 0x0 which cannot be believed as the MAC address.
I doubt that my MCU (STM32F103) may not be able to read proper data through SPI, is it correct?
I wonder what I can solve these problems.
