BLE Tracker about esp32_bletracker HOT 13 CLOSED

Not all the BLE devices are compatible, the scan check for the MAC Address of the device, and some devices have a changing BLE address (normally called random instead of public address) for privacy/security reason. The same for the reading of the battery level, the device has to expose the Battery Service (0x180F) and the Battery Level characteristic (0x2A19),
I have tested successfully with:

• nut mini (work both discovery and battery level).
• Amazfit bit (works only the discovery)
• Xiomi Mi Smart Band 4 (works only the discovery)

I bought a Redmond SkyTracker 08S tracker. Works. Displays the on and off status, and displays the RSSI signal strength. The battery status is always -1. Do I understand correctly that the battery status is not displayed for all devices? Although the app itself displays the battery level of the REDMOND RFT-08S tracker.

Yes, the battery level can be read only from the devices providing the Battery Service (0x180F) and the Battery Level characteristic (0x2A19), check the availability using a nRF Sniffer i.e. nRF Connect. Also in this case can happen the esp32 fails to pair with the device so the battery cannot be read. Unfortunately I haven't a lot of devices to test.
I will add your device to the list of working devices 😃

Installed nRF Connect and connected to the tracker. I didn't find a line about the battery. There are lines Generic Access, Device Name, Appearance, Peripheral, Preferred Connection, Generic Attribute, Nordic UART Service, TX Characteristics, RX Characteristics.

Within nRF Connect you have to connect to the discovered device (it can take a while) Then you have to search for the highlighted items.

Thanks for the screenshots, now everything is clear. Well, this is not critical, the main thing is that in your firmware I see the tracker and there is an on\off status. Added a mac to the white list and extra Macs are eliminated. Very convenient. For example, there is a firmware OpenMQTTGateway, it is useless, there is no normal connection with the tracker and a lot of extra. Thank you for the excellent firmware.

I connected the itag tracker. Only the status works, the battery level is not displayed, although through nRF Connect there is a display of the battery level. Will it be possible to display the battery level of the itag tracker?

These are the topics I have displayed in the MQTT client

from esp32_bletracker.

Perhaps the ESP is failing to connect to the itag unfortunately I haven't one to test. I have seen a similar issue with the nut (non nut mini) of another guy but I haven't found a solution yet.

from esp32_bletracker.

I forgot, obviously you have added the itag's MAC address to the list of the devices for which the tracker has to read the batteries, right?

from esp32_bletracker.

Вы не указали еще BLE трекер iTag. Данный трекер тоже обнаруживается в вашей прошивке.
You haven't specified the iTag BLE tracker yet. This tracker is also found in your firmware.

from esp32_bletracker.

Is the itag only discovered or is the battery value read also?

from esp32_bletracker.

Only iTag is detected, and the battery is not read. The value -1 is displayed.
Обнаруживается только iTag, а батарея не считывается. Отображается значение -1.
