Hi @bshannon ,
Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.
In fact, the SDK code already contains both the 5G and 2.4G code.
You can find the related comment:
/**
* Configure ED MAC mode in Wireless Firmware.
*
* \note When ed mac mode is enabled,
* Wireless Firmware will behave following way:
*
* when background noise had reached -70dB or above,
* WiFi chipset/module should hold data transmitting
* until condition is removed.
* It is applicable for both 5GHz and 2.4GHz bands.
*
* \param[in] wlan_ed_mac_ctrl Struct with following parameters
* ed_ctrl_2g 0 - disable EU adaptivity for 2.4GHz band
* 1 - enable EU adaptivity for 2.4GHz band
*
* ed_offset_2g 0 - Default Energy Detect threshold (Default: 0x9)
* offset value range: 0x80 to 0x7F
*
* \note If 5GH enabled then add following parameters
*
* ed_ctrl_5g 0 - disable EU adaptivity for 5GHz band
* 1 - enable EU adaptivity for 5GHz band
*
* ed_offset_5g 0 - Default Energy Detect threshold(Default: 0xC)
* offset value range: 0x80 to 0x7F

* \return -WM_FAIL if failed.

int wlan_set_ed_mac_mode(wlan_ed_mac_ctrl_t wlan_ed_mac_ctrl);
#define WLAN_ED_MAC_CTRL \
{ \
.ed_ctrl_2g = 0x1, .ed_offset_2g = 0x9, .ed_ctrl_5g = 0x1, .ed_offset_5g = 0xC \
}
wlan_ed_mac_ctrl_t wlan_ed_mac_ctrl = WLAN_ED_MAC_CTRL;
wlan_set_ed_mac_mode(wlan_ed_mac_ctrl);
Then, it is how to enable the 5G.
Please check the app_config.h, you can find the WIFI_88W8987_BOARD_AW_CM358_USD is also the 8987 chip.
#elif defined(WIFI_88W8987_BOARD_AW_CM358_USD)
#define WIFI_BT_TX_PWR_LIMITS "wlan_txpwrlimit_cfg_WW.h"
#define SD8987
#define SDMMCHOST_OPERATION_VOLTAGE_1V8
#define SD_TIMING_MAX kSD_TimingDDR50Mode
#define WIFI_BT_USE_USD_INTERFACE
#define WLAN_ED_MAC_CTRL \
{ \
.ed_ctrl_2g = 0x1, .ed_offset_2g = 0x9, .ed_ctrl_5g = 0x1, .ed_offset_5g = 0xC \
}
Then in the wifi_config.h, you can find :
#define CONFIG_5GHz_SUPPORT 1
wlan_txpwrlimit_cfg_WW.h, you can find the 5g cfg code:
#ifdef CONFIG_5GHz_SUPPORT
static wlan_chanlist_t chanlist_5g_cfg = {
.num_chans = 8,
.chan_info[0] =
{
.chan_num = 36,
.chan_freq = 5180,
.passive_scan_or_radar_detect = false,
},
.chan_info[1] =
{
.chan_num = 40,
.chan_freq = 5200,
.passive_scan_or_radar_detect = false,
},
.chan_info[2] =
{
.chan_num = 44,
.chan_freq = 5220,
.passive_scan_or_radar_detect = false,
},
.chan_info[3] =
{
.chan_num = 48,
.chan_freq = 5240,
.passive_scan_or_radar_detect = false,
},
.chan_info[4] =
{
.chan_num = 52,
.chan_freq = 5260,
.passive_scan_or_radar_detect = true,
},
.chan_info[5] =
{
.chan_num = 56,
.chan_freq = 5280,
.passive_scan_or_radar_detect = true,
},
.chan_info[6] =
{
.chan_num = 100,
.chan_freq = 5500,
.passive_scan_or_radar_detect = true,
},
.chan_info[7] =
{
.chan_num = 144,
.chan_freq = 5720,
.passive_scan_or_radar_detect = true,
},
};
#endifSo, my understanding is, if you enable the 5G symbol:
#define CONFIG_5GHz_SUPPORT 1
Then, you will can make the 5G works, as 8987 can support both 2.4G and 5G.
You need to include the related header file.
Wish it helps you!

I switched to the evkmimxrt1064_wifi_iperf sdk example. When I set the soft ap with this example it is able to support a network band of 5G. However, the protocol is not 802.11ac. Is there a way to acheive this protocol?
Hi @bshannon ,
Thanks for your effort.
Please tell me how do you readout the properties?
From the description, it mentions 802.11ac, is it the other wifi adpator to get the 8987 wifi properties?
I checked your module information:
https://www.murata.com/products/connectivitymodule/wi-fi-bluetooth/overview/lineup/type1zm
It list:
I check the code, it contains 11ac driver, then I think maybe need to check the details, whether the code calls that driver:
Best Regards,
Kerry
