Haas506 2.0 development tutorial -hota (only supports versions above 2.2)

1.hota.py upgrade

Case description

Use HTTP Protocol implementation OTA Air upgrade , Update the development board python Program . You only need to get the corresponding... Of the storage location URL You can update it .（ The case uses Alibaba cloud OSS demonstrate , Users can change the storage location as needed ）

（1） obtain URL

Upload the latest program to Alibaba cloud OSS. Get the name of the storage location URL.

1. take main.py and board.json The file is compressed into zip Format file
   
2. Alibaba cloud creation Bucket

3. Upload files zip file

4. Click on the details - Copy file URL( The time can be extended appropriately , After a timeout URL It will fail )

（2） Function code

Will duplicate url Fill in code
main.py

import utime as time
from modem import net
import hota
import network
import sntp
from modem import info
import system

pyversion="202204281243"
g_connect_status = False

def on_4g_cb(args):
    global g_connect_status
    pdp = args[0]
    netwk_sta = args[1]
    if netwk_sta == 1:
        g_connect_status = True
    else:
        g_connect_status = False

def connect_network():
    global netw,on_4g_cb,g_connect_status
    netw = network.NetWorkClient()
    g_register_network = False
    if netw._stagecode is not None and netw._stagecode == 3 and netw._subcode == 1:
        g_register_network = True
    else:
        g_register_network = False
    if g_register_network:
        netw.on(1,on_4g_cb)
        netw.connect(None)
    else:
        print('network register failed')
    while True:
        if g_connect_status:
            print('network register successed')
            break
        time.sleep_ms(20)

    time.sleep(5)
    ota_py_app()
    while True:
        print('httpota test')
        time.sleep(3)

（3） Output log

network register successed
csq: 31
pyversion:202203281800
------------------htp.pyfotaPy

# restart 
# Of the latest program log

2.hota.pac upgrade

Case description

• The firmware pac If necessary, you can chat privately
• Specific upgrade steps and py Upgrade similar

（1） obtain URL

Get pac After firmware package , The above method , take pac Package storage oss, Copy url.
