kamalesh posted a topic in Energia - MSPhi, I am using a MSP430FR4133 launchpad, i am trying to get a float value and send it via sim800. for that i hve to convert the float value to char* or char array. I have tried many conversions but i am not able to get the conversion properly. Even if i get it properly while printing it on the serial. The data is not transmitted in the right format through sim800. for example if i use dtostrf( buff , "%f" , flaotVal); function in serial monitor only "%f" is getting printed. and if i try other type of convertions , while transmitting through sim800 the right side part of the float value gets added to the decimal values . have tried ( itoa(), sprintf(), etc..) for example .. float value = 1.25. and if i tried converting and printing it on serial monitor i am getting it corrrectly as "1.25" . But when i am trying to transmit through sim800 the converted float value is sent as "0.125" instead 1.25 . Can anyone help me with this?.
