zephyr side shall be fine, atleast with this config set:

https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/Kconfig#L434

Not sure about the bluez side. I would recommend checking with their mailinglists.

Kind regards,

What about Long Range? Can Zephyr LR? And does the BlueZ 5.56 work with him adequately? Which commands and parameters?))

Hi,

I usually use some sort of bluetooth daemon, as its much easier than going directly on low-level.

Here's my output after finding the mac address of my advertising device ("power on", then issue "find -l")

[hci1]# add-device -t 2 C7:5C:54:47:7E:59

Pairing failed here, but the connection is kept afterwards.

btmgmt isn't very well documented, so I would recommend checking forums like stackoverflow etc for more info on this application.

Kind regards,

Håkon

How to connect (pair) le devices on btmgmt ?

sudo btmgmt --index 0

Next step scan:

[hci0]# find -l

After I found the right device, I try the pair command, but it connects via BR/EDR. What parameters do I need to connect LE?

>> pair [-c cap] [-t type] <remote address>

[-c cap] [-t type] - Is there a detailed description? how to LE pair?

[quote user="AlexandrX"]If you shorten TX on RX on raspberry pi4, everything works, forwards it to itself without distortion (on 1M speed)[/quote]

This is an OK proof-of-concept, but if you have any error in frequency; it will not be shown here. Please check the waveform by outputting "0xAA" / "0x55" over UART and see what the frequency is.

Or just test using 115k2 baud.

[quote user="AlexandrX"]

HCI-USB also tried, the result is the same, connects, after which you can only scan, and watch version information, and on this everything, when trying to set a local name or other configuration, we get IO error (*)...

[/quote]

As mentioned, you cannot change the name. it does not support that. This one also does not connect properly? How did you connect to the device??

I have tested both now, and using the "hci*" prefixed tools, I get strange results. By using bluetoothd, I'm able to successfully connect, and see the connection afterwards in hcitool:

$ sudo hcitool -i hci1 con
Connections:
	< LE C7:5C:54:47:7E:59 handle 0 state 1 lm MASTER AUTH ENCRYPT

note: I cannot use hcitool successfully for all functions; it can find devices but not create a connection. as this tool is deprecated, some features might not work anymore.

Kind regards,

Håkon

No converters used, connected to direct... UART TTL, U = 3.3V (Lgic 1)... If you shorten TX on RX on raspberry pi4, everything works, forwards it to itself without distortion (on 1M speed). On UART2 there are no restrictions and RTS/CTS it supports...

Interestingly, the regular BT (which is soldered on the RPI4) works perfectly, tunes, scans, etc.

RE: nRF52840-DK as HCI-UART based on zephyr issue

Håkon Alseth — Wed, 17 Mar 2021 14:29:41 GMT

Have you tried this on a PC running linux? Or by using hci_usb instead, or a different UART converter (USB/Uart one)? This might be a limitation with your rpi's uart interface / configuration. Is it even capable of doing 1MBaud?

Kind regards,

Håkon

Hi,

There's several tools that are deprecated by bluez, as shown in the first link:

There's a number of utilities in the upstream bluez bluetooth package that have long been deprecated with their functionality replaced by the core bluetoothctl utility. They're no longer receiving updates and at some point may be removed. Move these utilities to a dedicated sub package to indicate their upstream support status.

The list of utilities being moved are: ciptool gatttool hciattach hciconfig hcidump hcitool rfcomm sdptool

some features of those tools might not work with newer versions of bluez. newer tools are prefixed with "bt".

Please use newer tools.

[quote user="AlexandrX"]Attempting to set local name:
pi@raspberrypi:~ $ sudo hciconfig hci0 name xxx
Can't change local name on hci0: Input/output error (5)[/quote]

if you setup a terminal with btmon, you can see the debug information.

This particular response isn't responded to on my end.

Try using btmgmt --index <your index>

Then issue:

power on

find -l

You should get:

Discovery started
hci1 type 6 discovering on

and a list of discovered LE devices in your area.

Similar output here, it seems your manufacturer lookup table is old. that one belongs to the linux foundation.

Hi,

Could you try following the guide here?

From chapter "Using the BLE Controller with Linux's BlueZ" shows how to interface the hci device using newer bluez tools.

I tested 1M / 926100 / 115200 combine hwfc and no hwfc, -- the result is the same...
And yea, btattach - it just hangs until you interrupt it with a combination of Ctr+C.

RE: nRF52840-DK as HCI-UART based on zephyr issue

Håkon Alseth — Mon, 15 Mar 2021 12:56:28 GMT

Hi,

You shall use flow control with H4, as described in the description of the sample:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/bluetooth/hci_uart/README.html#overview

The baudrate of 921k6 is quite inaccurate, and you should rather use 1M baud. Here's the actual baudrate, as per the comment from nrf52_bitfields.h:

#define UART_BAUDRATE_BAUDRATE_Baud921600 (0x0EBED000UL) /*!< 921600 baud (actual rate: 941176) */

[quote user=""]sudo hciattach -t 5 -s 921600 /dev/ttyAMA1 any 921600 noflow nosleep[/quote]

hciattach is a deprecated tool, you should use btattach instead (with hwfc).

Kind regards,

Håkon
