Client initiates Data Sync automatically

[ihassin]

Client has automated process that syncs SOH data with the server twice a day.

Scenario: Retry to send SOH only at prescribed intervals Given the server has "5" items of type "A" When I update SOH with "Received" "A" "10" And I wait for the sync period at "01:00AM" But the sync fails And I wait for the sync period at "12:00PM" And the sync succeeds Then the server shows that there are "15" items of type "A" for my clinic

If we have time, I suggest that the times be read from a config file at run-time.

[ihassin]

From Bin: About the sync time, The local time on the tablet is not reliable. We never sync the time from app to the server, so 1 am or 12 pm on the tablet may not be the same with that on the server.

@garymabin : is there a process on the device that currently that runs on a scheduled time? If so, keep it. If not, please let me know ASAP.

Auto syncing even if it's not at the desired times is better than nothing. The operator will use the manual sync button during the day anyway. The server runs a batch script twice a day and that means that sometimes, it won't be up to date. I have not heard from Egwuma that this latency is a problem for the project.

On a related note, is it possible to force an automatic sync when the device is shutting down? This need not be developed now if it's high effort, but is it technically feasible and how much effort would it take if so?

@LakshmiCHAI : We should create a new card for this. However, I don't think we will have budget left to code and test a synch-on-shutdown like that.

[ihassin]

I think a story should be created for the backlog - we can then see if we can fit it in.

Done, see card 260

@ Itamar, the latency betweenw the server analytics run is not a a problem

[ihassin]

Following Bin's recommendation, we'd like to propose that we configure the tablet to sync SOH 4 times a day with the times for the sync ideally in a config file. @egwuma - please approve?

[ihassin]

OK - Config file is out of the question, and building a config retrieval service on the server is out of scope. We'll sync 4 times a day hardcoded in the code. I don't think it's a big issue doing so.

[ihassin]

This is ready for development, but should be picked up till 253 is at least code-complete

[garymabin]

Finish dev with #253

[chai-lmis]

can you please confirm the sync times, this will help in testing this card

[ihassin]

Looking at the source code, it looks like every 6 hours. Hope this helps.

[chai-lmis]

ok will check test this today

[chai-lmis]

Tested Ok for all commodities except 1 where the numbers did not add up - Hep.B Antigen (i emailed a screen shot)

[ihassin]

@garymabin any news on this please?

[garymabin]

@Ihassin, Will check it today

[ihassin]

@egwuma - we do not understand why a certain category was not synced. Maybe it's server side scripts? We need logs from transactions from the server side in order to investigate.

Also, please do not send info by email, rather paste here. I am referring to the screen shot. Please add it to this ticket.

[ihassin]

@egwuma - please note that the tablet does not show Heb.P; it means we don't have it locally, so that explains that the server did not update its values. Please make sure that server side API exposes HepB to client when asked for items.

[ihassin]

Auto sync was successful at 4am. Closing this ticket, and opening new ticket for Hep.B

[chai-lmis]

Tablet shows Hep. B Antigen, check again under vaccines category
