lovexoo7 opened this issue · comments
When set wifi channel in 5.8G band. in the promisc_callback, userdata parameter type field is not correct,but in 2.4G band is correct.
use IAR complier will cause promisc_callback function, the ieee80211_frame_info_t type filed will incorrect.
use GCC compiler will not happend.
after gcc complier, the type filed, alse has another value,but not 0 or 1, it`s a another, not stable.
the new isusse is rssi,sometime the rssi is 0,but rssi will not be zero.
how about this.
Current SDK is under test. Reported issues will be reviewed.
Many thanks to @lovexoo7
Hi @lovexoo7 the current SDK (under the release branch) have been tested and its working, there is no issue with the rssi value. Please refer to the image here: (https://forum.amebaiot.com/t/about-wifi-promisc-mode-promisc-callback-function-bug/718/13?u=daphwl)
Making changes to the code is also not recommended. Thanks!
If you want to check the rssi value in 5.8G band,
Under [component/common/api/wifi/wifi_promisc.c]
You can change this two line below from ch <=13 to ch <=161,
for(ch = 1; ch <= 13; ch ++)
for(ch = 1; ch <= 13; ch ++)
By default, all this should not be change.
If you want to try to modify any WLAN API, you can create a new function but this may affect the performance of the WLAN so it is not recommended.
