Revision 3 of the Mega ADK board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU(Device Firmware Upgrade) mode. Similar to the Mega 2560 and Uno, it features an ATmega8U2 program as a USB-to-serial converter.

It has 54 digital input/output pins (of which 15 can be used as PWM outputs) 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator a USB connection, a power jack, an ICSP header, and a reset button.
It has a USB host interface to connect with Android-based phones, base on the MAX3421e IC. The Atmel MCU ATMEGA16U2 MEGA 2560 R3 Improved Version CH340G Board is a micro-controller board base on the ATmega2560. If (netStatus.charAt(22) = '5' || netStatus.Digital I/O Pins 54 (of which 15 provide PWM output)įlash Memory 256 KB of which 8 KB used by bootloader When the code contains three or more exclamations it will prevent the sketch from being able to complete. So far it has been found to not occur with a Duemilanove, but three different Mega 2560s have gotten it to occur. This is an apparent bug with the Mega 2560. So now at Setup() i wait 10s for the module to boot up so it is ready to open a serial port, then i check if it is connected to the network before i send the commands to set into SMS mode.Įxample: // Initializing serial commmunication Using Mega 2560 - Bugs & Suggestions - Arduino Forum. I have a check for that and a reset function. what are Arduino mega 2560 or Genuino MEGA2560 boards Beginning with Genuino or Arduino MEGA 2560, The MEGA 2560 is intended for.

That command to set into SMS mode only works when you are connected to the network. Sometime when you are using Arduino mega Development Circuit board that is best of many Arduino Developed boards available by the device manager shows missing USB drivers for Arduino mega 2560 boards. In my case i have code that set the SIM module to SMS mode and to send those messages to the serial port.įor some reason it doesn't send them (or probably the module is not ready to accept them).Ĭonnecting the USB cable reset the arduino and run setup() when opening the serial monitor setting the module in the correct mode.Īdding this code in the main loop solves this issue even though i have them powered both by the same step down converter.Įdit: That turns out 1 hour later after debugging more is not exactly a proper solution to the issue.

Serial.println("Confirmication of phone number change sent") įor some reason it seems that while the MCU is running Setup() hardware or software serial don't work properly. String message = "Notification number set to: " + phoneNumber + "\nSend 'Help' for additional commands.\nNote in case of reset number returns to hardcoded default" Serial.println("Phone number set to: " + phoneNumber) The model number will be written on the largest black chip near to the USB jack. We need to know which USB to TTL serial chip is on your Uno.

PhoneNumber = textMessage.substring(9,21) Unable to update driver automatically, also manually i have arduino UNO R3 SMD Type. Set phone number to receive notifications Set module to send SMS data to serial out upon receipt
Another workaround which i need to test is to remove all Serial code (because i can in my specific project), but again this is not a proper solution.
This means you have to disassemble your project to access the resistor or add a switch if you want to use USB to debug later or upload new code. I found this which is related to the issue but not a proper workaround:Įdit: I can confirm using a resistor to short pins 0+1 together (serial) works but it is not a proper solution. The program will seem not to initialize serial in setup(). I am working on a project with a Mega 2560 and a Sim800L module.Įverything works fine, however if i don't connect the USB port (at least once) and power only externally (either by Vin unregulated 7-12V or 5V regulated pin)
