Hola , un gusto saludarte y felicitarte por la extraordinaria información que compartes, bueno comentarte que seguí al pie de la letra todo el ejemplo y no me pudo salir, al parecer no hay comunicación entre el SIM7000G con el ESP32 incluso por el pin 4 no envía la señal de POWER. Nota: la programación si se llega a completar, sin embargo no se prenden las luces de color rojo de GPS y del SIM. Lo que se queda prendido en todo momento es la luz de color azul y verde. Gracias por tu tiempo espero tu gentil respuesta y pongo en copia lo que me sale en en el monitor serial. rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1324 ho 0 tail 12 room 4 load:0x40078000,len:13508 load:0x40080400,len:3604 entry 0x400805f0 ets Jul 29 2019 12:21:46
Hello Friend , Thank you for your kind words . As per your written comments I can sense few thing might have happened and you can do few things for it i.e. Things to noted- 1. The green led indicates the power on board . 2. Blue Led indicates the Esp32 activity . 3. On other two led's , one which blinks shows the GSM network establishment and other red led shows power in GPS module . Give it a try - 1. Check whether device is properly working or not by uploading a simple blink program in esp32 . 2. Check the Usb cable you are using for communication. 3. Select correct baud rate . 4. Use latest version of Arduino Ide or try to use alternate version. I hope you find the solution for your problem. Good luck.
@@techwarmup Gracias por responder, realice lo me indicaste y la programación fue completada, sin embargo el ESP no responde, intento con varias programaciones y siempre sale lo mismo. rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1324 ho 0 tail 12 room 4 load:0x40078000,len:13508 load:0x40080400,len:3604 entry 0x400805f0 ets Jul 29 2019 12:21:46
Hello , Thank you for kind words , 1. First ,Which Sim Card you are using ? 2 . You can search APN in Google for whichever Operator's SIM Card you are using .
@@arnoldmuhairwe Yes you can use 3.3v pin but that won't be safe for the device if you got any voltage fluctuations device might collapse. As well as If you use multiple servo it won't provide enough current and voltage .
@@techwarmup I could use capacitors to smoothen the ripples and use a 3.3v LDO to supply a steady 3.3v supply. My worry is whether the GSM would be able to power up as well from that arrangement.

Do you mean firebase.google.com ? If yes then Yes you can send data to cloud using any suitable server like blueHost or AWS then you can fetch the data from server to your app or browser.
