H Hirogens Active Member Licensed User Longtime User Jun 22, 2018 #1 Hello, I prefer to say it now: I will have a lot of questions I have just finish my project (I recreate DFU OTA) Now I would like to perform the code and try to avoid some problem. That's why I would like to know if an alternative to sleep exist. Because when I use the sleep function, I think some process continue to run, and I would like something which put everything in pause. thanks !

H Hirogens Active Member Licensed User Longtime User Jun 22, 2018 #3 Hum I use Sleep only to wait informations: for example I send a command to my device (Create objet), when the objet is create I receive information about this command (01 to success and other for an echec). I can't send information while I haven't my objet correctly create. So I use Sleep to wait this. It's work but not perfectly that's why I would like something to do nothing while I haven't receive the information. I don't know if I do something like this it can work Code: Copy boolean = false send_command_create While boolean = false{} When I have response from the device an event is reach and I can see if the command is success and then set this boolean to false Upvote 0

Semen Matusovskiy Well-Known Member Licensed User Jun 22, 2018 #6 It seems to me the question is not about Sleep / Wait For as it is. I would like something which put everything in pause Click to expand... It's enough typical situation, when an app sends a request to server and waits a reply. During waiting time user's activity is undesirable. Something similar modal Msgbox. Well, it's relatively simple to prevent user's activity (WindowManager.LayoutParams) and screen rotation (ActivityInfo). Upvote 0

KMatle Expert Licensed User Longtime User Jun 23, 2018 #7 Don't add complicated ways just for a wait. Mostly it's enough to disable some views and post a message like "Please wait". On the other hand a server's response takes some milliseconds so there isn't a problem at all. Upvote 0

H Hirogens Active Member Licensed User Longtime User Jun 25, 2018 #9 Hello I don't know if resumable subs can help me: I send a command to my starter. Code: Copy CallSub(Starter, "recup_info_object") and this is the function in my starter Code: Copy Public Sub recup_info_object ManagerD.WriteData("0000fe59-0000-1000-8000-00805f9b34fb", "8ec90001-f315-4f60-9fb8-838830daea50", Array As Byte(0x06,0x01)) End Sub This command send to my device an instruction. When the device send to me the information that I ask this function Code: Copy Sub Manager_DataAvailable (Services As String, Characteristics As Map) CallSub3(Main, "DataAvailable", Services, Characteristics) End Sub handle the response, and in my main I treate the informations. If my command is a success I can continue the code. I have a lot of command like this and that's why I need to be sure to handle the response everytime. I don't know if it can help you more :/ Maybe you're right with resumable subs but maybe there is an other option =) Thanks ! Upvote 0
