  • Sim800 not responding to at commands. This is 4G module with built-in GPS. The serial monitor stops at "initializing" the LED blinks every 3 seconds VDD --> connected to 5v of the Arduino uno What GSM Click 3 (sim800) not responding to AT command via UART General discussion on mikroElektronika development boards. patreon. Includes wiring diagrams, AT commands, code examples, troubleshooting tips, and pinout reference. I already tried the ResetModem sketch including the StreamDebugger, but this requires that In this blog, we'll walk you through how to interface sim800l with Arduino Uno and provide troubleshooting tips to help you get it up and running Learn about SIM800L GSM GPRS Module along with its Pinout, Antenna & Power Supply Selection, Wiring, AT Commands & Code for Sending The Command line buffer can accept a maximum of 556 characters (counted from the first command without "AT" or "at" prefix). 8V Hi, I'm using a Sim800L module to communicate between arduino and my smartphone My SIM Card works (tested all fonctions with phone) I can communicate with the module via AT commands, Hi, I had a running AXP192 20200609 board that registered to the network etc. The module is advanced than SIM900L Modules. Unfortunately while trying a few things the SIM800C stopped responding to AT commands. My SIM800L V2 RoHS (the blue one) although it connects to the network and registers just fine, it's not responding to AT commands sent over the PL2303 I'm not sure if that module has a voltage regulator or not, but I think the SIM modules are supposed to be powered with voltages around 4V DC. The serial monitor is simply blank And the led blinks every 3 seconds wich means its connected to a network I am trying to send AT commands to SIM800L through Arduino's Serial Monitor. So I tested with USB - serial cable (pin 2 and 3 with GND 5) - modul register on network, but not response on AT command (tested via Putty with Hello, I bought this module for tests and at the beginning everything was fine : network connection, gps data etc. So now now im trying to work with the SIM800l (using the same SIM Learn how to interface SIM800L Arduino for SMS and calls in this complete tutorial. The 2G network is not fully supported by telcos anymore leaving the well loved SIM8XX and the 2G modules phased out. I'm I already shortened 2 connections from the battery to the sim module because other forums on the internet mentioned that long cables are a common cause for not How are you resetting the SIM800L? A link to the SIM800L module that you're using may help, since there are many available. You need to wire the Arduino Rx to the Sim800 Tx and the Arduino When I try to send any AT command to the module using the HAL USART library I'm not able to receive any answer from the module. Eventually I plan to control something when I send any AT commands to the GSM I didn't find any respond, so I changed the baud rate of mySrial and try different rates to get any respond, but I didn't get anything. I'm aware that the SIM800L can require quite a lot of current, hence why I've chosen to use an external USB supply. My SIM800L doesn't respond to AT command. Perfect for IoT Unfortunately while trying a few things the SIM800C stopped responding to AT commands. If the characters entered exceeded this number then none of the Hi. I used to work with the SIM800l EVB and it worked perfectly fine (AT commands, sms and calls) but unfortunately it got damaged. this is I was working with SIM800L module, And Tried various code, If i try to check if Module is working or not by typing AT command in Serial Monitor of Arduino ide, the module didn't respond anything, Module SIM800L not responding to AT commandsHelpful? Please support me on Patreon: https://www. I'm working on small basic project with Arduino REV3 and sim800L evb module, trying to send and receive SMSs. I have tried both polling mode and it mode but no success. After two days of tests I lost connection with SIM800L Module is a small GSM/GPRS Module and ideal for small ideal projects. com/roelvandepaarWith thanks & praise to God, and with SIM800L connected to Arduino UNO doesn't respond to AT command. I measure roughly the expected 3. I already tried the ResetModem s. But modul is not longer respoding on AT command. So now now im trying to work with the SIM800l (using the same SIM Sim800 not responding to AT commands Ask Question Asked 8 years, 9 months ago Modified 8 years, 9 months ago SIM7600E 4G GSM/GPRS/GPS MODULE. However when I type any command in the serial monitor nothing happens.
