Description

mfg_data

Custom manufacturer data

mfg_data_len

Manufacturer data length

Return value

- ESP_OK : Success - ESP_ERR_INVALID_ARG : Null argument

Notes

It is important to understand that length of custom manufacturer data should be within limits. The manufacturer data goes into scan response along with BLE device name. By default, BLE device name length is of 11 Bytes, however it can vary as per application use case. So, one has to honour the scan response data size limits i.e. (mfg_data_len + 2) < 31 - (device_name_length + 2 ). If the mfg_data length exceeds this limit, the length will be truncated.
