LILYGO T-SIM7000G ESP32-WROVER-B Solar Charge SIM GPS Antenna CH9102F 16MB 2G/NB TTGO Development Board

Review: Documentation d'utilisation et exemples d'utilisation très peu clairs - L'idée était -en fonction de la mort annoncée de la '2G', de remplacer des modules modem ne travaillant qu'en 2G (SIM800L, …) par des modules '4G' dans des applications IoT. L'objectif : recevoir et interprêter des SMS pour agir sur de la domotique en absence de connexion internet. SMS: Quand il s'ait d'émettre on trouve quelques exemples utilisables (Arduino IDE). Pour ce qui est de recevoir des SMS, je n'ai pas trouvé d'exemples opérationnels : - les bibliotèques usuelles (TinyGSM, …) ne traitent pas ce sujet; - aucun exemple complet exploitable - semble-t-il - même en commandes AT. Lacune qui rend excessivement difficile, sinon impossible l'exploitation de ce module À écarter pour l'instant, le travail de recherche s'avérant fastidieux et en finale - pour l'instant -improductif. Une immense déception qui ne pourra être comblé que quand le fabricant ajoutera dans ses exemples ce genre d'utilisation. [Edit 2023-04-23 :] Pour ceux qui désirent une connexion 4G, il vaut mieux envisager les cartes à base de A7670E ou - moins adaptées A7670A, voire la série des A7600x. En france, il faut privilégier les cartes offrant les connectivités LTE-FDD B3, B20 (4G les plus classiques pour les opérateurs nationaux). Le LTE-TDD peut être utile si on envisage un usage plus large que l'hexagone. En tous les cas, la consultation des datasheet (site de SIMCom) permet de lever le doute - en particulier sur les bandes de fréquences gérées en LTE (→4G)

## Questions & Answers

**Q: Are the gps & the lte antenas both included in the package with t-sim7000g ch9102f 16mb ? will lte antenna work in us?**
A: The package contains GPS and LTE antennas, LTE antennas can be used in the United States

**Q: What sim card/plans are you using in the usa? i'm looking for a low data option.**
A: I'm currently using Twilio.

**Q: Can you accommodate charging from the USB interface?**
A: FYI, I discovered that attaching or detaching power to the USB port causes the ESP32 processor to reset, while attaching or detaching power to the "solar" charge port does not disturb the processor.

**Q: Does this have any security chip? atecc608**
A: This product does not have this security chip

### ⭐⭐ Complicada de usar
*by C***N on 13 April 2024*

A priori, se ve una placa de desarrollo muy interesante al tener wifi, bluetooth GPS, GPRS, LTE… Sin embargo en la práctica la documentación y los ejemplos de uso no abundan y en cierto modo se ha quedado obsoleta. Si la piensas usar para MQTT sobre TLS, es un verdadero infierno. Recomiendo comprar la versión que lleva una TSIM 7600, con un juego de comandos AT mayor.
