= IPSP (Internet Protocol Support Profile) =
 +
This is *not* Bluetooth, bluetooth has '''fixed''' profiles such as A2DP https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Advanced_Audio_Distribution_Profile_(A2DP)
 +
 +
 +
The Generic Attributes ('''GATT''') define a hierarchical data structure that is exposed to connected Bluetooth Low Energy (LE) devices.
 +
 +
The Generic Attribute Profile (GATT) procedures define standard ways that services, characteristics and their descriptors can be discovered and then used to allow Bluetooth Low Energy devices to transfer data. The profile describes a use case, roles and general behaviors based on GATT functionality.
 +
===IPSP Profile===

IPSP is one of GATT https://www.bluetooth.com/specifications/gatt

Using rPi Zero W -> BLE -> 6LoWPAN -> XYZ to communicate over the Internet
IoT without Internet (Ip addresses) is *not* IoT !!!

  1. If you are on a laptop two(2) hci devices will show up, the first one is buggy
    hciconfig hci0 down
  2. Now you can try scanning for BLE devices

[edit] Creating a channel, capable of 6lowPAN (IPv6)

[RFC7668] "IPv6 over Bluetooth LE is dependent on both Bluetooth 4.1 and IPSP 1.0 or ..."


Reading http://blog.bluetooth.com/bluetooth-meet-the-internet-internet-say-hello-to-bluetooth you find that BLE uses Generic Attribute Profile (GATT) which is modular, and not Generic Access Profil (GAP) which is static and used by Bluetooth Classic.

GATT has many forms of which one is Internet Protocol Support Profile (IPSP) (Beware of HTTP Proxy Service (HPS) which is something completely different

Yep, 0x0c or 12 is for unsupported command. So the fw doesn't seem to  have support for LE. 
Let me get back to you on this, need to check up what fw is upon the repository. 

Note
   If using a Linux kernel version less than 4.0, the kernel debug file 6lowpan_enable will not be present. 
   Instead you should use "echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm" to set PSM channel as 0x23 (35),
   and enable the bluetooth 6lowpan module.

following the lowpan 802.15.4 blog

  • add

  • This is a strange page
    https://devzone.nordicsemi.com/f/nordic-q-a/14292/iot-sdk-rpi3---using-jessie-with-bluetooth_6lowpan

Now to establish my Bluetooth connection between the Raspberry Pis I run though the following steps: On the Master device I run the following commands: 

#need root access
sudo su

#enable 6lowpan over Bluetooth le
echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable

#start advertising Bluetooth LE service
hciconfig hci0 leadv

On the Slave device I run the following commands: 

#need root access
sudo su

#enable 6lowpan over Bluetooth le
echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable

#establish le connection to master
hcitool lecc 5C:F3:70:XX:XX:XX

The hcitool lecc command always returns “Connection Handle 64”. At this point I have a stable connection between the two devices that I can verify using the hcitool con command.

I am now able to run the following command on either the master or the slave where the mac address is the address for the Bluetooth device I am connecting too: 

echo “connect 5C:F3:70:XX:XX:XX 1” > /sys/kernel/debug/bluetooth/6lowpan_control

Whichever Raspberry Pi I run the command on establishes a 6lowpan connection and if I run the ifconfig command I see a new bt0 device.

Hi und danke erstmal,

bin jetzt soweit mit fast allen befehlen durch 

Code: [Auswählen]
pi@raspberrypi:~ $ ls -l /dev/ser*
lrwxrwxrwx 1 root root 7 Feb 28 23:59 /dev/serial0 -> ttyAMA0
lrwxrwxrwx 1 root root 5 Feb 28 23:59 /dev/serial1 -> ttyS0

das sieht schon mal gut aus, lt. deinem Howto
allerdings bekomme ich dennoch kein Device : 

Code: [Auswählen]
pi@raspberrypi:~ $ hcitool dev
Devices:
pi@raspberrypi:~ $ hcitool scan
Device is not available: No such device
pi@raspberrypi:~ $ 

glaub bin zu müde oder zu blind.
habt Ihr eine Idee ??

danke

so alles was mit Bluetooth zu tun hat gelöscht und folgendes getan

Code: [Auswählen]
sudo apt-get install raspberrypi-sys-mods

sudo apt-get --reinstall install pi-bluetooth

sudo shutdown -r now


dann 

Code: [Auswählen]
sudo systemctl start hciuart.service
pi@raspberrypi:~ $ systemctl status hciuart.service

und siehe da!!!

es geht!!

danke an alle!

[edit] IPSP (Internet Protocol Support Profile)

This is *not* Bluetooth, bluetooth has fixed profiles such as A2DP https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Advanced_Audio_Distribution_Profile_(A2DP)


The Generic Attributes (GATT) define a hierarchical data structure that is exposed to connected Bluetooth Low Energy (LE) devices.

The Generic Attribute Profile (GATT) procedures define standard ways that services, characteristics and their descriptors can be discovered and then used to allow Bluetooth Low Energy devices to transfer data. The profile describes a use case, roles and general behaviors based on GATT functionality.

[edit] IPSP Profile

IPSP is one of GATT https://www.bluetooth.com/specifications/gatt

[edit] Maybe a hint on how to detect whats IPSP, and whats not

Code snippet from https://github.com/NordicSemiconductor/Linux-ble-6lowpan-joiner/blob/master/src/bluetooth_6lowpand.c 

===/*  Parse EIR events for IPSP device. */===
static bool parse_ip_service(uint8_t *eir, size_t eir_len, char *buf, size_t buf_len)
{
	size_t offset = 0;
	bool ipsp_service = false;
	bool ssid_correct = false;
	uint8_t val[256];

	memset(val, 0, 256);

	while (offset < eir_len) {
		size_t field_len = eir[0];

		switch (eir[1]) {
		case EIR_UUID16_SOME:
		case EIR_UUID16_ALL:
			put_le16(IPSP_UUID, &val[0]);
			if (!memcmp(val, eir + 2, field_len/2))
				ipsp_service = true;
			break;
		case EIR_NAME_SHORT:
		case EIR_NAME_COMPLETE:
			if (field_len - 1 > buf_len)
				break;
			memcpy(buf, &eir[2], field_len - 1);
			break;
		case EIR_MANUF_SPECIFIC_DATA:
			put_le16(NORDIC_COMPANY_ID, &val[0]);
