#### socket.dnsserver(*, dnsIndex, ip_addr)
When no arguments are passed this function returns the configured DNS servers Primary (Index=0) and backup (Index = 1)
to set primary and Backup DNS servers specify the Index and Ip Address.
Example:
```
>>> socket.dnsserver()
('10.0.0.1', '8.8.8.8')
```
Setting DNS servers:
```
>>> socket.dnsserver(1, '0.0.0.0')
>>> socket.dnsserver()
('10.0.0.1', '0.0.0.0')

This method is used to set up the LTE subsystem. After a `deinit()` this method can take several seconds to return waiting for the LTE modem to start-up. Optionally specify a carrier name. The available options are: `verizon, at&t, standard`. `standard` is generic for any carrier, and it's also the option used when no arguments are given.
#### lte.deinit\(\)
#### lte.deinit\(detach=True, reset = False\)
Disables LTE modem completely. This reduces the power consumption to the minimum. Call this before entering deepsleep.
#### lte.attach\(\*, band=None\)
- `detach` : detach from network.
Enable radio functionality and attach to the LTE Cat M1 network authorised by the inserted SIM card. Optionally specify the band to scan for networks. If no band \(or `None`\) is specified, all 6 bands will be scanned. The possible values for the band are: `3, 4, 12, 13, 20 and 28`.
- `reset` : reset LTE modem.
#### lte.attach\(\*, band=None, apn=None, cid=None, type=LTE.IP, legacyattach=True\)
Enable radio functionality and attach to the LTE network authorised by the inserted SIM card. Optionally specify:
- `band` : to scan for networks. If no band \(or `None`\) is specified, all 8 bands will be scanned. The possible values for the band are: `3, 4, 5, 8, 12, 13, 20 and 28`.
- `apn` : Specify the APN (Access point Name).
- `cid` : connection ID, see `LTE.connect()`. when the ID is set here it will be remembered when doint connect so no need to specify again
- `type` : PDP context type either `LTE.IP` or `LTE.IPV4V6`. These are options to specify PDP type ‘Packet Data protocol’ either IP [Internet Protocol] or IPV4V6 ver4,6 , that depends actually on what does the Network support.
- `legacyattach` : When kept = True the API `LTE.isattached()` will return True when attached to the Network AND Network registration status is home or roaming, when flag is False, API `LTE.isattached()` will return True when attached to the Network only.

*NOTE* :
When carrier is specified in `LTE()` or `LTE.init()` (eg. `lte = LTE(carrier=verizon)`) No need to specify band, apn or type these parameters are already programmed in to the LTE modem for each carrier.

#### lte.isattached\(\)
Returns `True` if the cellular mode is attached to the network. `False` otherwise.
#### lte.dettach\(\)
#### lte.detach\(reset=False\)
Detach the modem from the LTE Cat M1 and disable the radio functionality.
- `reset` : set to True to reset the LTE modem.

Send an AT command directly to the modem. Returns the raw response from the modem as a string object. **IMPORTANT:** If a data session is active \(i.e. the modem is _connected_\), sending the AT commands requires to pause and then resume the data session. This is all done automatically, but makes the whole request take around 2.5 seconds.

Perform a hardware reset on the cellular modem. This function can take up to 5 seconds to return as it waits for the modem to shutdown and reboot.
#### lte.pppsuspend\(\)
Suspend PPP session with LTE modem. this function can be used when needing to send AT commands which is not supported in PPP mode.
#### lte.pppresume\(\)
Resumes PPP session with LTE modem.
#### lte.factory\_reset\(\)
Reset modem configuration to Factory settings.
#### lte.modem\_upgrade\_mode\(\)
Puts the modem in to modem upgrade mode and bridging LTE modem UART port to FiPy/GPy UART0 to enable upgrading Firmware over USB port.

#### lte.reconnect\_uart\(\)
Reconnect esp32 UART 2 to LTE modem UART port.
#### lte.ue\_coverage\(\)
Check Network Coverage for UE device (i.e LTE modem).
`True`: There is Network Coverage.
`False`: No Netwok Coverage.
