Taking long time to scan multiple devices

[muhammadfaheem-pycom]

Hi, guys, I am trying to config 5 devices but your sample app taking up-to 3 minutes to complete the scanning. the app scans 2 devices very soon like in the first 6 seconds but remains 3 takes 3 minutes.

Hi, After testing, all 5 devices can be successfully configured with network, the interval time is not as long as you described.
The Broadcast mode can get stuck because it's so heavily used, so check out the Broadcast environment.

Can you please explain how the broadcast true and broadcast false works?

Broadcast and Multicast are two modes of sending data.

On the EspTouch project:
The IP address of a Broadcast is 255.255.255.255. This IP address represents all IP addresses in the same subnet.
Multicast IP address is 234.1.1.1 ~ 234.100.100.100, one-to-one group communication between hosts.

I have some improvement.

1. There is sleep time after scanning is completed so I think there should be more protocols method to do business logic according to the life cycle of scanning.
   for example

• (void) scanningWillSleep()
• (void) scanningDidSleep()
• (void) scanningWillAwake()
  etc.

2. Also if I want to repeat the scanning infinite times like until the user stops it by self otherwise scanning should repeat again and again. So you guys are using getTotalRepeatTime variable I want it should support -1 value for infinite times.

1. EspTouch does not have a scan, UDP data is sent, and the device receives the data and distributes the network.

2. If you want to send data without timeout, you can remove the timeout in the "__execute" method of the "esptouchtask" class.
