Re: Modifying library for the WSSFM10 Sigfox module for compatibility with STM32L476RG

i have upload a new example for STM32L476RG to the library in case anyone need this: #include <Tinyfox.h> #define btn PC13 // boton usuario azul / blue user button #define RXLED PA5 #define rstPin PC12 //nucleo-64 STM32L476RG: //HardwareSerial Serial2(USART2); HardwareSerial Serial3(USART3); Tiny<Ha...

Re: Modifying library for the WSSFM10 Sigfox module for compatibility with STM32L476RG

you dont get the message on the sigfox backend? are you sure the module its connected to the right Tx and Rx pins? your modules have leds to let you know when its transmitting? also, you are using the wisol.send_rcv() funtion, if you dont have a downlink configured use wisol.send() I commented out:...

Re: Modifying library for the WSSFM10 Sigfox module for compatibility with STM32L476RG

in your module you have a reset pin beside the Vcc pin (marked in blue in the graphic). connect that to the nucleo board on some free pin.
this pin its necessary to wake up the module after its put in sleep mode
load the code and push the user button.

Re: Modifying library for the WSSFM10 Sigfox module for compatibility with STM32L476RG

try this configuration: HardwareSerial Serial3(USART3); //connect the modulo to serial3. Tiny<HardwareSerial,HardwareSerial> wisol(&Serial3,&Serial,PA1,false); //change PA1 to match your reset pin. . . . #define btn PC13 //change this to PC13 the blue/user button on the nucleo #define RXLED ...

Re: STM32L476RG for low power application

thank you GonzoG i am now able to read the battery voltage with accuracy. my next problem is decreasing the current drawn by the circuit. currently, after i call to LowPower.deepSleep(60000*suenno_minutos); the current lower to a 500uA. this seem too much current. how could i lower this? currently i...

Re: Modifying library for the WSSFM10 Sigfox module for compatibility with STM32L476RG

a friend and i wrote a library for the wisol modules. we call it TinyFox. the blue pill example should be compatible with minimal modifications you can find it here: https://github.com/TECA-IOT/Tinyfox or at the library manager : ) just change HardwareSerial Serial2(USART2); //this is the default se...

STM32L476RG for low power application

im trying to use my new nucleo-64 for a low power application (trying to make it run on batteries for months, having it in sleep mode most of the time waking it up periodically to read sensors and log data). but i need to clarify some doubts: 1) what would be the best voltage to drive it? 1.8 o 3.3v...

Re: STM32L476RG Serial Messup

I've tested your code,note that I've clean it: HardwareSerial Serial1(USART1); HardwareSerial Serial3(USART3); HardwareSerial Serial4(UART4); HardwareSerial Serial5(UART5); void setup() { Serial5.begin(9600); Serial5.println("serial 5"); Serial4.begin(9600); Serial4.println("serial 4...

[solved] STM32L476RG Serial Messup

i just got a new nucleo-64 STM32L476RG. im trying to control multiple Serial slaves via the multiple uart ports on the nucleo. the problem its most of the serial ports are printing through the USB adapter. only uart3 its printing over its respective pin. uart4 its not printing at all. here its my co...
