Hello to all Geeks,
I am beginner to BLE technology since kindly help me out by clearing the issue
i am trying to add a new GATT service to x-cube ble ("http://www.st.com/web/en") ,but unfortunately the service is not shown in the ble debugger (https://play.google.com/store/apps/details?id=com.adatronics.bledebugger&hl=en)
the service which is already exits in that code is visible ,but a new one with new uuid is not forming
/************************************ Ref code *********************************************************/
(under main)
ret = Add_UV_Sensor_Service();
if(ret == BLE_STATUS_SUCCESS)
PRINTF("Environmental Sensor service added successfully.\n");
else
PRINTF("Error while adding Environmental Sensor service.\n");
(under service .c)

Perhaps you do not call the function Add_UV_Sensor_Service() in main.c file where there is a space for initializing the services.

I want to use PJSIP's C API to record the incoming audio to a file on a machine with no hardware sound device .
I'm unsure about the details, but the sparse documentation for PJSIP suggests it should be
possible through the pjsua_set_null_snd_dev() call.
In the fully functioning (Windows biased) example below the call pjmedia_aud_dev_default_param(PJMEDIA_AUD_DEFAULT_CAPTURE_DEV, ¶m) returns PJMEDIA_AUD_INVALID_DEV in the status.
The code generates this same error on Linux (Ubuntu 14) and Windows 10 when there are no hardware audio devices present.
If there is an hardware audio device driver installed the exact same code works fine on both OSes.
I have compiled the PJSIP libraries with PJMEDIA_AUDIO_DEV_HAS_NULL_AUDIO enabled.
On Linux the presence of the module snd-dummy does not help.
How do I get access to the audio data stream from a SIP call after calling pjsua_set_null_snd_dev()?

Apologies to the pure of heart for the mix of C and C++ above.
Solved this by loading the Alsa module snd-dummy.
Look in /lib/modules/YOUR_KERNEL_VERSION/modules.dep if its mentioned.
If you have it then load it with modprobe snd-dummy
Otherwise recompile your Kernel to include it as a module or follow the installation in the link above.
I tried to compile static binary using latest Gstreamer Libs 1.8.0. I want to get incomming RTSP stream and put it into file. The pipeline is:

As the source is RTSP with SDP data - I don't need to set caps manually. Interesting part that running this pipeline using Gstreamer 0.10 works fine.
Fixed by myself. Gstreamer doesn't complain about missing plugins if you dont use them in pipeline directly. Static registration of plugins udp and rtpmanager solved the problem.
We are using libmodbus library to read register values from energy meter EM6400 which supports Modbus over RTU. We are facing the following two issues.
1) We are facing an issue with modbus_read_registers API, this API returns -1 and the error message is:
ERROR Connection timed out: select.
After debugging the library, we found this issue is due to the echo of request bytes in the response message.
read() API call in _modbus_rtu_recv returns request bytes first followed by response bytes. As a result, length_to_read is calculated in compute_data_length_after_meta() based on the request bytes instead of response bytes (which contains the number of bytes read) and connection timed out issue occurs.
We tried to use both 3.0.6 and 3.1.2 libmodbus versions but same issue occurs in both the versions.
2) modbus_rtu_set_serial_mode (ctx, MODBUS_RTU_RS485) returns "BAD file descriptor".
Please confirm if there is any API call missing or any parameter is not set correctly.
Our sample code to read register value is as follows.
int main()
{
modbus_t *ctx;
uint16_t tab_reg[2] = {0,0};
float avgVLL = -1;;
int res = 0;

if (rc == -1) {
printf("Read registers failed: %s\n", modbus_strerror(errno));
res = 1;
}
for (i=0; i < 2; i++) {
printf("reg[%d]=%d (0x%X)\n", i, tab_reg[i], tab_reg[i]);
}
avgVLL = modbus_get_float(tab_reg);
printf("Average Line to Line Voltage = %f\n", avgVLL);
modbus_close(ctx);
modbus_free(ctx);
}
}

Issue 1) is probably a hardware issue, with "local echo" enabled in your RS-485 adapter. Local echo is sometimes used to confirm sending of data bytes on the bus. You need to disable it, or find another RS-485 adapter.
I have written about this in the documentation of my MinimalModbus Python library: Local Echo
It lists a few common ways to disable local echo in RS-485 adapters.
I have been writing a lcd kernel driver for a LCD module. All was going well, I can write to the display, create a /dev/lcd node that I can write into and it will display the results on the screen. I thought using the llseek fops callback to position the cursor on the lcd would be good, this way I could use rewind fseek etc. However it is not working as I expected, below is a summary of what I am seeing:
The relevant lines of code from the driver side are:
loff_t lcd_llseek(struct file *filp, loff_t off, int whence)
{
switch (whence) {
case 0: // SEEK_SET
if (off > 4*LINE_LENGTH || off < 0) {
printk(KERN_ERR "unsupported SEEK_SET offset %llx\n", off);
return -EINVAL;
}
lcd_gotoxy(&lcd, off, 0, WHENCE_ABS);
break;
case 1: // SEEK_CUR
if (off > 4*LINE_LENGTH || off < -4*LINE_LENGTH) {
printk(KERN_ERR "unsupported SEEK_CUR offset %llx\n", off);
return -EINVAL;
}
lcd_gotoxy(&lcd, off, 0, WHENCE_REL);
break;
case 2: // SEEK_END (not supported, hence fall though)
default:
// how did we get here !
printk(KERN_ERR "unsupported seek operation\n");
return -EINVAL;
}
filp->f_pos = lcd.pos;
printk(KERN_INFO "lcd_llseek complete\n");
return lcd.pos;
}
int lcd_open(struct inode *inode, struct file *filp)
{
if (!atomic_dec_and_test(&lcd_available)) {
atomic_inc(&lcd_available);
return -EBUSY; // already open
}
return 0;
}
static struct file_operations fops = {
.owner = THIS_MODULE,
.write = lcd_write,
.llseek = lcd_llseek,
.open = lcd_open,
.release = lcd_release,
};
int lcd_init(void)
{
...
// allocate a new dev number (this can be dynamic or
// static if passed in as a module param)
if (major) {
devno = MKDEV(major, 0);
ret = register_chrdev_region(devno, 1, MODULE_NAME);
} else {
ret = alloc_chrdev_region(&devno, 0, 1, MODULE_NAME);
major = MAJOR(devno);
}
if (ret < 0) {
printk(KERN_ERR "alloc_chrdev_region failed\n");
goto fail;
}
// create a dummy class for the lcd
cl = class_create(THIS_MODULE, "lcd");
if (IS_ERR(cl)) {
printk(KERN_ERR "class_simple_create for class lcd failed\n");
goto fail1;
}
// create cdev interface
cdev_init(&cdev, &fops);
cdev.owner = THIS_MODULE;
ret = cdev_add(&cdev, devno, 1);
if (ret) {
printk(KERN_ERR "cdev_add failed\n");
goto fail2;
}
// create /sys/lcd/fplcd/dev so udev will add our device to /dev/fplcd
device = device_create(cl, NULL, devno, NULL, "lcd");
if (IS_ERR(device)) {
printk(KERN_ERR "device_create for fplcd failed\n");
goto fail3;
}
...
}
To test the lseek call I have the following unit test:
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#define log(msg, ...) fprintf(stdout, __FILE__ ":%s():[%d]:" msg, __func__, __LINE__, __VA_ARGS__)
int lcd;
void test(void)
{
int k;
// a lot of hello's
log("hello world test\n",1);
if (lseek(lcd, 0, SEEK_CUR) == -1) {
log("failed to seek\n", 1);
}
}
int main(int argc, char **argv)
{
lcd = open("/dev/lcd", O_WRONLY);
if (lcd == -1) {
perror("unable to open lcd");
exit(EXIT_FAILURE);
}
test();
close(lcd);
return 0;
}
The files are cross compiled like so:

I cannot figure out why the parameters are being mucked up so badly on the kernel side, I tried to SEEK_CUR to position 0 and in the driver I get a SEEK_SET (no matter what I put in the unit test) and a crazy big number for off?
Does anyone know what is going on please ?
btw I am compiling for kernel 2.6.29 on a arm dev kit
OK sorry guys after trying to debug this all last night it comes down to compiling against the wrong kernel (I had KPATH left to a different config of the kernel than was on the sdcard)
sorry for wasting everyones time, but hopefully if someone is seeing what looks like a crazy stack in their kernel driver this might set them straight.
oh and thanks for all the help :)
anybody care to share some insights on how to use LSP for packet modifying ?
I am using the non IFS subtype and I can see how (pseudo?) packets first enter WSPRecv. But how do I modify them ? My inquiry is about one single HTTP response that causes WSPRecv to be called 3 times :((. I need to modify several parts of this response, but since it comes in 3 slices, it is pretty hard to modify it accordingly. And, maybe on other machines or under different conditions (such as high traffic) there would only be one sole WSPRecv call, or maybe 10 calls. What is the best way to work arround this (please no NDIS :D), and how to properly change the buffer (lpBuffers->buf) by increasing it ?

SOCKET s,
LPWSABUF lpBuffers,
