Re: SIM800L + UART + network module?

I took some time to review my code and I believe you haven't called the connect funciton. ppp.connect() from machine import UART, Pin import network def send_command(command): command = command + '\r\n' uart.write(command) line = uart.read(100) if line: line = line.decode('utf-8') print(line.replace...

Re: SIM800L + UART + network module?

Try putting sleeps here: from machine import UART, Pin import network def send_command(command): command = command + '\r\n' uart.write(command) line = uart.read(100) if line: line = line.decode('utf-8') print(line.replace('\r\n','\n')) else: print('Hmmm...') uart = UART(1, 9600, timeout=2000, rx=17,...

Re: SIM800L + UART + network module?

Try using either of these commands to have the simcom module allow the takeover of the TCP/IP stack: ATD*99# or AT+CGDATA="PPP",1 You can google these commands as well to find out more information. So your code would look like this: from machine import UART, Pin import network def send_command(comma...

Nonblocking MQTT may be found here.
Thank you for the reply and the non-blocking mqtt.

Does network.PPP also block asyncio?

uasyncio, PPP, and uMQTT - Blocking?

Good afternoon everyone! I would like to explore the topic of PPP, uMQTT and, uAsynio in relation to eachother. I finally got my ESP32 and Simcom 7000g board to use the PPP interface and I am able to periodically send information over MQTT (umqtt.simple). Now I wish to apply this PPP interface into ...

Re: MQTT using transparent mode on Cellular modem (SIM7000g)

So, I have thought of an idea in order to use the transparent mode of my cellular modem on UART 1. I am looking for feedback on this general idea as I am having trouble sorting through the higher level conceptualization of this. I am looking to make a sort of proxy server on the ESP32 that handles t...

Re: MQTT using transparent mode on Cellular modem (SIM7000g)

@kevinkk525 After some more fiddling today I think you are right with the idea of scripting the AT commands and using the Simcom 7000g's MQTT protocol. I am asking for a whole bunch of trouble by trying to use libraries that are not designed for this type of use. I am going to be doing more research...

MQTT using transparent mode on Cellular modem (SIM7000g)

Good morning friends! I am working through a proof of concept idea for adapting MQTT libraries to use the transparent mode of my cellular modem. Topology: ESP32 connected to Cellular modem (SIM7000g) via UART 1. Then modem goes into transparent mode after connecting to my MQTT server. This means ALL...

Re: Full List of Args for network.WLAN(network.AP_IF)

Thank you both for your replies. I really appreciate the time. I am slowly getting the full picture of how micropython works on the ESP32 and 8266. It is one thing to program for it and another to understand the whole process including ESP-IDF and the Kernel of ESP's etc. So forgive me if I ask igno...
