Using NB-IoT base station to connect to Blynk cloud

Blynk Servers Blynk Cloud
#1

Hello everyone,

Iā€™m considering a project where I would use the platform Arduino MKR NB 1500 that uses an NB-IoT module. From the examples I have looked at, connecting the device to the Blynk cloud has been done through Ethernet/Cellular shield or USB connection, but would the Blynk library work if I sent information from device to an NB-IoT base station deployed in my city? Meaning would my instructions from device to blynk server and vice versa be reached if I use IoT network?

You can try this new NB_Generic which provides this Advanced example NB_Blynk.

Why do we need this NB_Generic Library

This library is based on, modified, bug-fixed and improved from:

  1. MKRNB Library

to add support to many boards besides Arduino MKR NB 1500.

This NB_Generic Library will finally provide these following features (certainly ony if supported by the NB/GPRS modules)

  1. TCP Client and Server (HTTP, HTTPS , MQTT, Blynk, WebSockets, ā€¦)
  2. UDP data connections
  3. SMS (Sending and Receiving)

Currently Supported modems

  • u-blox LTE-M/NB-IoT Modems (SARA-R4xx, SARA-N4xx, but NOT SARA-N2xx). Not fully tested yet.

To be Supported modems

  • SIMCom LTE Modules (SIM7100E, SIM7500E, SIM7500A, SIM7600C, SIM7600E)
  • SIMCom SIM7000E/A/G CAT-M1/NB-IoT Module
  • SIMCom SIM7020E/A/G CAT-M1/NB-IoT Module
  • Sequans Monarch LTE Cat M1/NB1 (VZM20Q)

Releases v1.0.0

  1. Initial coding to add support to many boards besides MKRNB 1500 / u-blox NB-IoT / LTE-M modem SARA R401

I have one sim7020G,when I can use it with blynk?

Iā€™d appreciate support for the SIM7020E. It appears on your todo list @khoih

BTW I gave up on the MKRNB 1500 a year ago. Unreliable connections, hard to troubleshoot. The SIM7020E is trouble free - apart from lack of support for Blynk and TinyGSM.
