Problem getting BLE manufactoring ID

Postby rob_legierse » Wed May 18, 2022 9:44 am

Hi,

I try to get the ble manufacturing id from a connected device. Is this possible?
I can get the manufacturing id's with a ble scan before connecting with esp_ble_gap_set_scan_params and esp_ble_gap_start_scanning but i want to scan after connecting and I know the ble address to get the manufacturing id from.

When i start a scan after connecting i get the error:
E (10434) BT_APPL: bta_dm_ble_set_scan_fil_params(), fail to set scan params.
E (10444) BT_HCI: CC evt: op=0x200b, status=0x7

Do i need a scan or is there an other possibility to retrieve the manufacturer id when already connected?

ESP-IDF v4.4
ESP32-C3
I started from the esp_hid_device example

Thanks, Rob
