Read the MAC address
-
Hello @kl3m3n,
This subject is already old and at the time I asked about the MAC address, and from what I see, it seems I did not answer the reason for the question, I apologize, I answer now.
Why is it important to receive some unique information from the cell phone or Gui-O, it always depends on the type of use in which we use the Gui-O.
Scenario, example: I have 100 employees with Gui-O installed on their cell phones, as well as 500 IoT hardware installed at various locations, to which all employees can connect. At any given time, one of the employees may resign or even be let go. It would be in best interest to be able to receive this unique information to be able on the hardware side (Esp32) to bar access to this terminated employee.
The situation being resolved in a list on the Mqtt server does not seem to me to be the most appropriate, at least for this scenario.Thank you
Best regards -
@Sato Hello!
What about using the user id parameter under "General settings -> User settings". Give your users unique user ids. This parameter is also sent with each MQTT message (prefixed by usr:).

Hello @kl3m3n, hope you are well
In this submenu "User settings" I always put the name of the employee, which I can change whenever I want, which is
very well. Even if i barred the employee's name in the hardware(esp32), the employee would only need to change the name in User settings to be able to log in again.So, the issue I raised in the previous post, can only be solved through a unique data from Gui-O, such as for example "Application UUID", or a random number that is created during the installation of the Gui-O or the cell phone's MAC, or any other that is possible.
I think the random number 0001.... 9999, if possible, is a good solution.Best regards

@Sato Hi,
I will check what is the best solution to do this... I will get back to you.

@Sato Hi,
your suggestion is not possible as the numbers could repeat...
I will add an option to send also the "Application UUID", which will be disabled by default. You will be able to enable sending this value through the "Developer mode" menu.
Is this ok?

@Sato Hi.
Version 1.0.41 has the option to send unique application id. You need to enable this from the developer menu.

Hi @kl3m3n,
I appreciate your readiness to evaluate and whenever possible implement our needs.
Have enabled the develop mode and the Send IoT device name, but the App UUID not appears on Serial Monitor.
it is necessary to invoke it with some command?Best regards

@Sato said in Read the MAC address:
Send IoT device name
You need to enable "Send IoT app uuid" (last entry, below "Send IoT user name", try scrolling down). You need to use version 1.0.41.

Hi @kl3m3n,
mqttClient.publish(&In[0], "@appUuid\r\n");
I forgot that this command already existed, I just thought that when opening the App it would automatically send the App UUID as it does with "Init", or am I looking at this the wrong way?
Best regards
