ESP32 client iBeacon Scan read major/minor and RSSI

[fjfuente13]

Hi, try to scan iBeacon with an ESP32. I do it and I can read some parameters but major and minor, no. I will use major and minor, to filter the devices found. But when use sketch of blescan, I can’t be able to read major and minor. Please, any idea? Thanks in advance (I just star with iot, and my knowledge are limited.)

Hi. In theory you could create BLEBeacon variable, then use this function with reaw advertising data: https://github.com/chegewara/esp32-snippets/blob/master/cpp_utils/BLEBeacon.cpp#L59

Then use functions to get data you need: https://github.com/chegewara/esp32-snippets/blob/master/cpp_utils/BLEBeacon.cpp#L36-L52

Raw advertisement data you can get with this function: https://github.com/chegewara/esp32-snippets/blob/master/cpp_utils/BLEAdvertisedDevice.h#L42

Just remember to change uint8_t* to std::string.

Hi, thanks for the answer.

I've tried what you tell me, but when I add it to the bluetooth scan, all the data that tells me are 0.

In any case, I have found another way to get the data: (attached, in case it's useful for someone)

char md = BLEUtils::buildHexData(nullptr, (uint8_t)advertisedDevice.getManufacturerData().data(), advertisedDevice.getManufacturerData().length());

thank you and greetings,
