Wifi is OK (pings works), but scanning is very poor.
I use ESP32-C3, so according to docummentation:
https://docs.espressif.com/projects/esp ... ce-feature
I only need to enable CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE in menuconfig.
Is something that i can do for scaning improvement?
What should i set in disc_params?:
Code: Select all
disc_params.filter_duplicates = 0;
/**
* Perform a passive scan. I.e., don't send follow-up scan requests to
* each advertiser.
*/
disc_params.passive = 1;
/* Use defaults for the rest of the parameters. */
disc_params.itvl = 0;
disc_params.window =0;
disc_params.filter_policy = 0;
disc_params.limited = 0;
rc = ble_gap_disc(own_addr_type, BLE_HS_FOREVER, &disc_params,
blecent_gap_event, NULL);
My sensor sends one advertising frame every 10s. and on each port change. Most of advertising packets is not received.
Is there any way to calculate what is the interval and window of BLE scanning wiyh CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE=y ?
Meaby my sensor should send data twice with calculated time interval? But how to calculate what this interval should be?
I'm planning to move this code (BLE scanning) to RainMaker if it start to work reliably in this modified 'bleprph_wifi_coex' example.
