Hi @comcom, You meant that how to know that application was installed successfully on the device? You can check that on your device using “app status” command or from the Airvantage checking the status of “install application”. Regards, Muralidhara N. ---

Hi @muralinagraj, I followed document and i stucked at step 4 of 9.1 Overlay Legato Apps section (SOTA). My app like below (check picture out). It’s in “in progress” and nothing. What should i do now ? I checked connection between device and Airvantage by AT commad line" AT+WDSS=1,1" and it return "OK, +WDSI: 4, +WDSI: 6, WDSI: 23, 1" ![l2](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/1X/1acdf9010126e2dfd4fb164d56edc2a3c1c62098.PNG) ![l1](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/1X/4c2937e01479df2d5f78fc7b463f5b096e09c6eb.PNG) ![L3](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/1X/6ea70eb55fe1577798be59d4e7dabb1a2dcc1055.PNG) ---

Hi @comcom, Your AT command results says your device is able to connect to Airvantage successfully. Now, Can you please cancel those instances of “Install application - In Progress”, Then fallow the below steps and check if you are able to install application. 1.Install the application with settings as shown in attached screen shot ![install_App](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/1X/72657e20a819f8bf464fa0ddc79e4b40bb467fc2.png) 1. Then try to connect to Airvantage using the AT command(AT+WDSS=1,1). Regards, Muralidhara N.
