[W52P+W56P] Same base station with with different handset models - Auto-provisioning

[Lucia_Yealink]

Dear Sir,

Do you mean you want to upgrade the handset firmware of W52 and W56 in the same time, right?

In the wui, we can only upgrade W52H or W56H in one time. But we can use the parameter 'over_the_air.url' via auto provision to update the firmware at the same time. Please see the detail below:

1.upload the firmware of W52H and W56H, in my side,26.73.0.10 is for W52H,61.80.0.1 is for W56H

2.configure a cfg1 file, add this parameter in cfg1 file:
#!version:1.0.0.1

over_the_air.url = http://10.2.2.21:8099/26.73.0.10.rom

auto_provision.server.url = http://10.2.2.21:8099/cfg2.cfg

3.configure a cfg2 file, add this parameter in cfg2 file:
#!version:1.0.0.1

over_the_air.url = http://10.2.2.21:8099/61.80.0.1.rom

4. add the auto provision URL in server URL(in mt test, it is http://10.2.2.21:8099/cfg1.cfg) via web interface.
click on auto provision now, it will ask for the auto provision server, and download cfg1 file, upgrade W52H to 26.73.0.10, and it also ask for another provision server URL.

5.in this test,firstly,W52H will upgrade to 26.73.0.10, and base will obtain the second provision server URL after upgrading, and it will download cfg2 file, upgrade W56H to 61.80.0.1
then all is done. it may spend some time to upgrade. So we use a nested auto provision way to access it.
