SSL Connection to AWS IoT from ESP8266(Micropython)

It looks really different
try to remove all MQT files from card and use internal one.

internal files are already on your device as frozen modules.

Dear @livius i have downloaded simple.py from following link below and added file into my board.
https://github.com/micropython/micropython-lib/tree/master/umqtt.simple/umqtt
I have imported library as follows;

from simple import MQTTClient

Error as follows;

Do you have any idea about this error, why it could be happened?

@sunrise17
I do not know and becouse of that try first internal one.
Remove all mqt files from your flash and do simple

from MQTTClient import MQTTClient

and use it then

[sunrise17]

@livius Yes i have tried it also but after i got this error i have left it. "ImportError: no module named 'MQTTClient''. Because mqtt lib is not coming with Esp32 Firmware in default.

[livius]

@sunrise17 said in SSL Connection to AWS IoT from ESP8266(Micropython):

Esp32

it come with pycom firmware
what firmware version do you have?

import os
os.uname()

[sunrise17]

@livius

OS Info as follows;
(sysname='esp32', nodename='esp32', release='1.9.3', version='v1.9.3-286-gbbb08431 on 2018-02-09', machine='ESP32 module with ESP32')

@sunrise17
You must update the firmware first.
https://pycom.io/downloads/

You have 1.9 but current is 1.15 and frozen mqt go with 1.10

[sunrise17]

@livius, i am using oem esp32, is it possible to update it with pycom firmware update?,

I have tried but it has not been updated

[livius]

@sunrise17

sysname='esp32', nodename='esp32',

then you are on the wrong forum, for this device better go to micropython forum

is it possible to update it with pycom firmware

it is possible to flash it with custom pycom firmware
i say custom because you must modify firmware first, especially about chip revision.

[sunrise17]

Dear @livius , is there some guide to upload custom pycom firmware to ESP-WRoom-32 board? Because you have mentioned that it is necessary to adjust chip revision. I will be glad if you let me know about some guide to flash my board with pycom firmware. Thanks...

[livius]

@sunrise17
you must modify esp_get_revision - i do not have guide but on the forum you can find such posted by
