Dear Friends,
I am using HID Prox Pro Reader (6005) to which is integrated with Microcontroller (XMC4500 Infineon IC). I am able to read card data properly. But sometimes without card swapping interrupt is generated and card data is formed which should be declared invalid.
But I dont know how...
Hi Alex,
Thanx for helping me!!!!!!!!!!!!!!!!!!!!!
I will try this. Do u have an idea that sim908 may send garbage data because i used the array very careful means there may be very rare situation that array index out of bound situation will occur. In short if u are aware about this ,please...
HI friends,
I am facing one problem communication port of sim908 is connected to xmc controller but sometimes the garbage data is received from uart of controller which is in connection with sim908 i also checked commands , string termination but still i am facing that problem some time ...
Hi Friends
I am confused that how to check whether response is came fully or not i can not decide i checked that how many times the <LF> came i count that when it is three times for a command response. so i am in very dangerous situation how to resolve it is there any flag which can indicate...
Hi Friends
I am facing one problem in my gps tracker system. When i am sending the AT+HTTPACTION=1 command to gps i am not getting responce what is the problem please help me i am in very trouble situation .............................
Please tell me if any one can resolve this problem...
Hi Friends
Thanx for giving me support but now i dont know whether they are at same level but i am getting data from uart of sim908 still i am facing one problem data from gps is recieved in mode 0 that is AT+CGPSINF=0\r the reply is 0,0.000000,0.000000,0.000000,2................ LIKE wise data...
Hi friends,
I am using Sim908 for my application and i am capturing data from gps antenna and i want it in mode 0 <mode>,<long>
<latt>......................................................... but i am not getting proper data that is gps data is lilke something...
Actually if u are using microcontroller then there is no need to connect rs232 cable we can directly connect the rx and tx pins of Microcontroller and sim908 and can read reply of gsm from rx pin of mcu.
Hi Friends,
Friends i am facing the problem that i want to power on the sim908 which is done by pin3 of sim908 called POWERKEY and it is connected to pin83 of STM32F103VE to port D's pin 0 for that i tried to set the BSRR register of PORTD to 1 for 1 second by using delay. and also there is...
Hi Friends,
I know without sim908 we can not send AT COMMANDS but i want to interact by microcontroller of stm32f103ve and in my application board UART OF stm32f103ve is connected to UART of sim908 (pin15 and pin16) i tried to send the command by UART TX PIN OF stm32f103ve but the problem is the...
Hi Friends,
I am new for sim908 ,i have stm32f103 microcontroller and USART1 of microcontroller is connected to sim908's microcontroller so i dont know how to interact with sim908 by stm32f103 i read AT COMMANDS but i cant interface with sim908 and unable to send AT COMMANDS please if anybody...
Hi Friend,
sorry for asking i am new user but i am currently working on gps system by which interface these AT commands are sent i have microcontroler of stm stm32f103 but i dont know how to send these AT COMMANDS please if u have solution u can send me ...please please and also where to see...
