 Installation

 ------------

 To install am7020:

 ```python

 import upip

 upip.install('micropython-am7020')

 ```

 or

 ```console

 $ ampy -p COMX put am7020

 ```

 ## MQTT 教學說明

 Declare nb and mqtt client instance using:

 ```Python

 nb = AM7020NB(uart_num=0, baudrate=115200, tx_pin=16, rx_pin=17, reset_pin=5, dump_at_cmd=False)

 mqtt = AM7020MQTT(nb)

 ```

 Initialize nb and connect to NBIOT base station:

 ```Python

 while((not nb.init() or (not nb.nbiotConnect(apn, band)))):

     print(".")

 

 while(not nb.waitForNetwork()):

     print(".")

     sleep(5)

 ```

 Check MQTT connection status and connect to Broker:

 ```Python

 if(not mqtt.chkConnBroker()):

     mqtt.connBroker(MQTT_BROKER, 1883, mqtt_id="MY_AM7020_TEST_MQTTID")

 ```

 Publish and subscribe:

 ```Python

 mqtt.publish(TEST_TOPIC, "Hello MQTT")

 

 def callback1(msg):

     print(TEST_TOPIC, ":", msg)

 mqtt.subscribe(TEST_TOPIC, callback1)

 ```

 Listen for messages from the broker:

 ```Python

 mqtt.procSubs()

 ```

 ## HTTP 教學說明

 Declare nb and http client instance using:

 ```Python

 nb = AM7020NB(uart_num=0, baudrate=115200, tx_pin=16, rx_pin=17, reset_pin=5, dump_at_cmd=False)

 http = AM7020HTTP(nb, HTTP_SERVER)

 ```

 Initialize nb and connect to NBIOT base station:

 ```Python

 while((not nb.init() or (not nb.nbiotConnect(apn, band)))):

     print(".")

 

 while(not nb.waitForNetwork()):

     print(".")

     sleep(5)

 ```

 HTTP GET and POST:

 ```Python

 http.get(HTTP_GET_API)

 state_code = http.responseStatusCode()

 body = http.responseBody()

 

 http.post(HTTP_POST_API, content_type="application/json", body="{\"value\": \"POST\"}")

 state_code = http.responseStatusCode()

 body = http.responseBody()

 ```
