I'm using a Minew G1 Gateway to collect both beacons and BLE devices.
Doing some test, I see that it detects beacons and various devices (smart TVs, smartwatches) but I can't find any of smartphones nearby. I find several unknown devices, but their mac address doesn't correspond with those of my phones.
Smartphones used are at least 4.2 bluetooth version.
Do you have any idea about what I'm doing wrong?
As Emil said, you need an app to enable BLE adverts on smartphones to make them discoverable to scanning devices. Have a look at the links below:-
BLE is working between two mobile phones

I have a Bluetooth Low Energy Android app project here which works fine so far for most of my android smartphones. I use my BLE weather thermometer in my app anywhere within my room, it works.
Except for a Huawei P30 Lite deivce: With my Huawei I can not get a connection, except I place the BLE Thermometer on my right upper corner on my Huawei smartphone. I assume the Bluetooth antenna is located there in my smartphone?
Under linux I can configure my wifi transmission power like:
sudo iwconfig wlan0 txpower 30mW
Is there such a possibility to configure my Bluetooth Low Energy Android library?
It is not obvious from your question where the problem is. Typically in Bluetooth you have control of the power the peripheral advertises at, so that would be the BLE weather themometer in your case.
I would suggest looking at the HCI logs on the phones to see if they give more insight as to what the issue is.
I'm quite new in Arduino and Bluetooth devices, but need to demostrate some vulnerabilities of IoT devices and I want to try hack HC-06 bluetooth controller to send instruction to Arduino. I want to try MAC spoofing method and second method is about exploiting advertisement channels of BLE devices by sniffing. I don't actually know if HC-06 is considered as BLE device or if it has advertisement channels.
I'm really new in this field and I've just read some articles about basics. This is used as a school project.
HC-06 is not a BLE device, is Bluetooth v2.0 + EDR and it does not has advertisement channels.
Go for HM-10 to have a proper BLE device.
Some references that may help you to get into the topic:

When I make a BLE device talk to an Android device, is there a way for the android device to distinguish what advertising channel the BLE device is on? If doing so is impossible in Android, is it possible with Adafruit BLE devices?
No, it's not. The information is discarded before the advertisement packet is sent by the receiving Bluetooth controller to its host (Android) over hci. Why do you want this info anyway?
It seems you can do it on Adafruit though, since it uses nRF softdevice, which gives you this info.
I'm wondering whether or not we can make a specific BLE peripheral device with having this ability to be supported by iOS/Android for automatic scanning for automatic reconnecting, i.e without using any extra app.
I think some standard BLE accessory devices (like Heart sensor) are already known by smartphones, so after first-time pairing, the smartphone's OS itself will scan for finding them again automatically for re-connecting each time when the connection gets lost.
Yes. If the device is a HID device then the system will auto connect to the device until you disable it in Android and unpair it in iOS.
But what's the purpose if you don't have an app?
I would like to control an Arduino device with a Motorola phone.
I have a Lilypad (preferred), an Uno, and a Mega Arduino board and I have two Motorola phones (a Droid Bionic and a Droid Razr Maxx) both running Android 4.1.2. According to an App called "USB Host Diagnostics" neither phone has USB Host Mode capability.
A variety of sites suggest the problem is that the phone doesn't provide enough power to the Arduino. Their solution requires cutting up and reconnecting the wires inside the cables. Others say the creation of a special "dongle" solves the problem, as long as it is in the phone when it starts to boot up but is removed before it finishes. Others suggest that it requires rooting the phone, which I'm afraid is probably beyond my comfort level and skill set. And many of these postings are several years old.
Has anyone figured out an smarter/better way to either enable or work-around the host mode capability issue of these phones? Or would it just be easier to find a used Nexus or Galaxy phone?
