So I guess its time to toss this out there, has anyone imagined a proceedure to remotely update firmwares, weather it be updates, cwe or full image spk files without going through AirVantage as we cannot use it in our scenerio?.. thoughts, ideas and inputs welcome…

Hi,

> Hi Nila, You should be able to get your FTP working using the lib curl. The sample use of libcurl for HTTP Get request is already available in the HTTPGET sample. Following the HTTP Get sample you should be able to build the FTP client code using curl. Below is FTPGET c example code using curl which should provide you the quick reference to get started: [https://curl.haxx.se/libcurl/c/ftpget.html](https://curl.haxx.se/libcurl/c/ftpget.html) Below is a command line example if you wish to give a quick try over the command line: [http:/…](http://linux.byexamples.com/archives/320/using-curl-to-access-ftp-server/)

ok read that thread, but what exactly is thie process to use the update tool in the target to install the application. ?? i can get the spk on the device easily via scp but… flashing it from inside the device… kinda not really understanding it
Once your application is downloaded in the target over FTP, you can use the update tool in the target to install the application.

```
avcDaemon.avcDaemon.le_update -> .le_update
```

Why don’t you directly use modify the avcService application?
It is already working fine.

I just have a try to add that line in modemDemo app, I don’t see problem:
```
bindings:
{
send.sendComponent.send -> modemDemo.demoComponent.send
modemDemo.demoComponent.le_mdc -> modemService.le_mdc
modemDemo.demoComponent.le_mrc -> modemService.le_mrc
modemDemo.demoComponent.le_sim -> modemService.le_sim
modemDemo.demoComponent.le_sms -> modemService.le_sms
modemDemo.demoComponent.le_data -> dataConnectionService.le_data
modemDemo.demoComponent.le_update -> .le_update
}
```
And in the .cdef file, you need to add " le\_update.api":
```
requires:
{
api:
{
modemServices/le_sms.api
modemServices/le_mrc.api
modemServices/le_mdc.api
modemServices/le_sim.api
le_data.api
le_update.api
}
}
```
