Cannot access some members of wifi_pkt_rx_ctrl_t (IDFGH-10820)

[aldardou]

Answers checklist.

• [X] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• [X] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• [X] I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.2-dev-1962-g53ff7d43db

Operating System used.

Linux

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

None

What is the expected behavior?

I expected it to be able to access the value of all public members of wifi_pkt_rx_ctrl_t and I can access many (e.g. rssi, timestamp, mac, rate) and I expect to be able to access cwb and sig_mode the same way. They are defined in the same struct.

What is the actual behavior?

Instead when building the project so far only for the fields cwb and sig_mode the compiler claims error: 'wifi_pkt_rx_ctrl_t' {aka 'esp_wifi_rxctrl_t'} has no member named 'cwb'.

Steps to reproduce.

In my csi_callback function I try to read out as much information about my read CSI data as possible (all of them except cwb and sig_mode actually work). Here is the relevant code snippet causing the issue:

uint8_t* csi_buffer = (uint8_t*)csi_info->buf;
uint16_t csi_length = csi_info->len;
wifi_pkt_rx_ctrl_t csi_meta = csi_info->rx_ctrl;
unsigned csi_chan = csi_meta.channel;
signed csi_rssi = csi_meta.rssi;
unsigned csi_timestamp = csi_meta.timestamp;
uint8_t* smac = csi_info->mac;
unsigned csi_rate = csi_meta.rate;
//After here is where it starts being fishy
unsigned channel_bandwidth = csi_meta.cwb;
unsigned csi_sig_mode = csi_meta.sig_mode;

Please note that for C6 there is a different definition of the hardware packet header, due to https://github.com/espressif/esp-idf/blob/53ff7d43dbff642d831a937b066ea0735a6aca24/components/esp_wifi/include/esp_wifi_types.h#L442-L443 and the definition for C6 is here: https://github.com/espressif/esp-idf/blob/53ff7d43dbff642d831a937b066ea0735a6aca24/components/esp_wifi/include/esp_wifi_he_types.h#L204

Thank you igrr. :) I was not aware of there being a different definition. This makes it clear why I was not able to access the meta data I was looking for, therefore I will close this issue.
