B4J Question RPI jserial problems /dev/ttyACM0

[javiman6969]

I have this problem too (std::bad_alloc).
Raspberry PI 2 with a USB Dongle,

Bus 001 Device 004: ID 0451:16a6 Texas Instruments, Inc. BM-USBD1 BlueRobin RF heart rate sensor receiver

I have correctly open /dev/ttyACM0 but closing the port, the result is (std::bad_alloc).

I use the last verison of JSSC and jSerial 1.06
Any suggestion?

Thanks!

Hi. Thanks for your answer.

IF i use this code:

  spRF.Initialize("spRF")     
  spRF.Open("/dev/ttyACM0")
  spRF.SetParams(115200,8,1,0)                                         
  astreamRF.Initialize( spRF.GetInputStream,  spRF.GetOutputStream, "astreamRF" )

  ....
  ....
  ....

  astreamRF.Close
  spRF.Close

The result is the next error:
what(): std::bad_alloc

If I comment the line:

  'astreamRF.Initializeprefix( spRF.GetInputStream, True, spRF.GetOutputStream, "astreamRF" )
  'astreamRF.Close

Perfectly opens and closes the port and does not give an error.


I have reviewed all the post but nothing.
Any other suggestions?
Thanks!!!

You shouldn't use prefix mode here. Prefix mode can only work when the other side of the connection also uses prefix mode.
