Find devices with custom service like in central_hr example #bt #ble

Phil Hipp
 

Hi,

I'm trying to port the central_hr example to my project. In this project I'm using a peripheral that advertises a 128Bit UUID of a custom service instead of the 16Bit UUID of the HRS service. I also want to parse the AD data as in the example to build a list of all scanned devices that support this custom service. What do I have to change in the example for that purpose?

Also how can I read/write and subscribe to characteristics of that service?

Best Phil

Is it possible to Upgrade a bare metal firmware(not from zephyr, may be from nrf sdk example) through smp server explained in zephyr project ?


Re: SPI on nRF52-PCA10040 possible? #nrf52832

moritzgerlich@...
 

Hi Joe,
thanks again for your fast answer.

I tried to run spi_loopback/spi.c
on nrf52840_pca10056 but i am still running into problems.

I will explain the problem, if someone has the time to take a short glimpse over it, i would very much appreciate it.

The idea/goal is just to send data via spi_transceive.
To do so i changed the main method to setup the tx and rx buffers
as well as struct device *spi_fast.

The spi_config is setup before with:

struct spi_config spi_cfg_fast = {
    .frequency = FAST_FREQ,
    .operation = SPI_OP_MODE_MASTER | SPI_MODE_CPOL |
    SPI_MODE_CPHA | SPI_WORD_SET(8) | SPI_LINES_SINGLE,
    .slave = SPI_SLAVE,
    .cs = SPI_CS,
};

I also added CONFIG_SPI=y in the nrf52840_pca10056.conf file.

The main method is:

void test_main(void)
{
//setup the buffers here
    const struct spi_buf tx_bufs[] = {
            {
                .buf = buffer_tx,
                .len = BUF_SIZE,
            },
        };
        const struct spi_buf rx_bufs[] = {
            {
                .buf = buffer_rx,
                .len = BUF_SIZE,
            },
        };
        const struct spi_buf_set tx = {
            .buffers = tx_bufs,
            .count = ARRAY_SIZE(tx_bufs)
        };
        const struct spi_buf_set rx = {
            .buffers = rx_bufs,
            .count = ARRAY_SIZE(rx_bufs)
        };
//finishesd setting buffers

//setup the device
    struct device *spi_fast;
    spi_fast = device_get_binding(SPI_DRV_NAME);
//finished setting up device

//check parameters
    printk("%s\n",SPI_DRV_NAME);
    printk("%i\n",SPI_SLAVE);
    printk("%i\n",SLOW_FREQ);
    printk("%i\n",FAST_FREQ);
//finished checking parameters

    int ret;
    ret= spi_transceive(spi_fast, &spi_cfg_fast, &tx, NULL);

    if (ret) {
        SYS_LOG_ERR("Code %d", ret);
    }

    printk("Still alive and trying.\n");
}

The problem is, that if i flash the board i get the following output:


The program hangs at spi_transceive and never reaches printk("Still alive and trying.\n");

However if i set ret= spi_transceive(spi_fast, &spi_cfg_fast, &NULL, &NULL); so output is set to NULL i get:




Does someone have an idea what is going wrong?


Thanks again.


How to setup BCSP at runtime with manufacture specific commands #bt #protocol #hc5 #bcsp

Stefan Jaritz
 

Hej,

I like to implement an firmware upgrade via bcsp + manufacture specific commands. I give a quick setup of my system:

BT device <---> UART3  @ MCU <---> Zephyr OS

The update process works in following steps:

- open uart3 9600,N,8

- send "DFU"

- open uart3 115200,E,8

- establish a link via bcsp

- sending and receiving the manufacturer specific commands on channel 12

Now comes my question: How to do this with Zephyr OS?

I saw a implementation of the HC5 protocol:

https://github.com/zephyrproject-rtos/zephyr/blob/master/drivers/bluetooth/hci/h5.c

Think I may can use this, because it is said, that the bcsp can be used in combination with HCI HC5. Am I right?

The dfu commands using channel 12 of the bcsp. For me seems that function "static int h5_queue(struct net_buf *buf)"  is only handling cmd/event and acl messages. How to it is dealt with all the other ones? ( acl = 6, cmdEvt = 5, sco = 7, le = 1, ack = 0,  dfu = 12)


Kind regards!

Stefan


Re: SPI on nRF52-PCA10040 possible? #nrf52832

Johannes Hutter
 

Hi Moritz,

SPI does not have DTS support in nordic boards yet, so you still have to set it up via Kconfig until https://github.com/zephyrproject-rtos/zephyr/issues/8758 is completely resolved.

The first part of

zephyr/tests/drivers/spi/spi_loopback/boards/nrf52_pca10040.conf

should be a good starting point for your case. You have to set CONFIG_SPI=y then.

Regards,
Joe

I want to connect the nRF52-PCA10040 to another board via SPI. However i cannot

Did someone use SPI with one of the nRF52XX boards and would have an
idea (or a sample code) for using/setting up the SPI device?

Thanks in advance for any kind of help!

Re: MPU FAULT when starting BLE peripheral sample on nrf52840_pca10056

Chettimada, Vinayak Kariappa <vinayak.kariappa.chettimada@...>
 

As you see your toolchain is not correctly picking the gcc libraries from armv7e-m.

 

I am not on my MacBook now, hopefully someone else could help you resolve the issue or will help set the CFLAGS explicitly.

Thank you for letting me know.

 

May be others in the community can follow up on the original issue with the toolchain from SDK-ng.

Hi, 

Did you, "Look for the “-L … “ option supplied when compiling."???
What folder path do you have? Incorrect library supplied will cause the hardfault when div operations is performed.

Hello,

I'm trying to run the BLE peripheral sample of the zephyr v1.12.0 branch on the NRF52840 PCA10056 DK. I built the sample under macOS 10.13.6 using the arm-zephyr-eabi toolchain built with sdk-ng on that machine.

Re: MPU FAULT when starting BLE peripheral sample on nrf52840_pca10056

Bøe, Sebastian <Sebastian.Boe@...>
 

Hi, about the possible lib gcc toolchain issue.

Of the available gcc.a, I am using the one suffixed with '#' when
using the sdk. Note that it seems that this is different on your
machine.

./fpu/libgcc.a
./armv6-m/libgcc.a
./libgcc.a
./thumb/libgcc.a
./armv7-m/libgcc.a
./armv7e-m/fpu/libgcc.a
./armv7e-m/fpu/fpv5-sp-d16/libgcc.a
./armv7e-m/fpu/fpv5-d16/libgcc.a
./armv7e-m/libgcc.a ##################
./armv7e-m/softfp/libgcc.a
./armv7e-m/softfp/fpv5-sp-d16/libgcc.a
./armv7e-m/softfp/fpv5-d16/libgcc.a

And when using 'ZEPHYR_TOOLCHAIN_VARIANT=gccarmemb' I get:

./libgcc.a
./thumb/v7e-m/fpv4-sp/softfp/libgcc.a
./thumb/v7e-m/fpv4-sp/hard/libgcc.a
./thumb/v7e-m/libgcc.a ##############
./thumb/v7e-m/fpv5/softfp/libgcc.a
./thumb/v7e-m/fpv5/hard/libgcc.a
./thumb/libgcc.a
./thumb/v8-m.main/libgcc.a
./thumb/v8-m.main/fpv5/softfp/libgcc.a
./thumb/v8-m.main/fpv5/hard/libgcc.a
./thumb/v8-m.main/fpv5-sp/softfp/libgcc.a
./thumb/v8-m.main/fpv5-sp/hard/libgcc.a
./thumb/v6-m/libgcc.a
./thumb/v7-ar/fpv3/softfp/libgcc.a
./thumb/v7-ar/fpv3/hard/libgcc.a
./thumb/v7-ar/libgcc.a
./thumb/v8-m.base/libgcc.a
./thumb/v7-m/libgcc.a
./hard/libgcc.a


Relevant commands:

grep LOAD b/zephyr/zephyr.map
find . -name libgcc.a

AFAIK it is possible to use ZEPHYR_TOOLCHAIN_VARIANT=gccarmemb on mac.
I would recommend this over ZEPHYR_TOOLCHAIN_VARIANT=xtools.

From the docs:

"In case a toolchain is not available for the board you are using, you can build a toolchain from scratch using crosstool-NG. Follow the steps on the crosstool-NG website to prepare your host"
"http://docs.zephyrproject.org/getting_started/installation_mac.html#using-a-3rd-party-toolchain"

Hey,

thanks a lot so far. What are the correct gcc libs that should be used?

What folder path do you have? Incorrect library supplied will cause the hardfault when div operations is performed.

Re: native_posix on Windows?

Amir Gonnen
 

I did some progress but the issue is not resolved.
The issues I've seen were:
  • Windows newline format 
  • In Linux gcc creates ELF image, while on windows gcc creates COFF image. Zephyr explicitly assumes ELF format in several places (in gen_offset_header.py for example).
  • On COFF inline assembly looks a little different, for example the usage of .scl, .type etc. (inline asm in gcc.h)
  • COFF format automatically adds underscore to symbols. Some symbols are defined in ldscript and referred to in the sources. Either an underscore needs to be removed from the sources or added to the ldscript.
  • __in_section_unique passes __FILE__ to the section declaration which makes the assembly code invalid (it doesn't like a name built from quoted path)
After working around all the above issues I got to the point where build completes successfully and creates an executable image (Yay!).
Unfortunately it does not run, Windows claims this is not a valid executable. Something probably still needs to be changed on the ldscript to make it a valid PE image, I'm not sure what.

Unless anyone has some inputs, I'm going to stop this effort for now.
Just for the reference I'm attaching a patch with my workarounds.

Amir
