Re: nrf52840 ble error #ble #nrf52840

Is this custom hardware? Are you implying that both interfaces work independently but not together?

Zephyr rtos : Unable to scan all broadcasted BLE packets #ble #hci #nrf52480 #samples #uart

Mayank <mayank7117@...>

#6862

Hi All,

I have observed one thing related to zephyr's hci_uart sample application.
I have used above application to implement the logic of beacon scanning in my custom application.
(Used Bluez 5.50 from host side. Nordic's nrf52840_pca10056 chip with zephyr's hci_uart app flashed in it).

Now, my concern is, I have got one beacon which has a default advertising interval set to 900ms.
So, At least i should get 1 broadcated BLE packet per second.

Case-1 :
- I'm scanning the beacon using 'nrf Connect' android mobile application.
- Here, i can see that packets are being received with adv interval gap of 500ms-900ms roughly.
- i.e, Ar least 1 packet per second.

Case-2 :
- While scanning through my application for consecutive 10 secs, I hardly receives 1 or 2 packets.
- Why is it so ? Ideally, At best i should get 10 samples in 10 secs.

Is there any issue with zephyr or Nordic's nrf52840?
Is it possible that the broadcasted packets are not falling in the physical channels 37,38,39 for being scanned, because of which the beacon packets are missing?

Thanks,
Mayank

Hi,

Iam using nrf52840 development board, developing software using zephyr.
In software development iam using bluetooth as a peripheral and uart in interrupt mode(to get data from other module), when iam trying to run both interfaces the getting below errors and iam included watchdog timer so after sometime it is restarting.

West 0.7.2 can't work

FrankLi

#6859

Dears,
After I update west to 0.7.2, the west can't work for any command, include --help. It alwasy show:

File "/home/frank/.local/bin/west", line 11, in <module>

sys.exit(main())

File "/home/frank/.local/lib/python3.6/site-packages/west/app/main.py", line 767, in main

When I remove the "requires_workspace=False" of __init__ in below files, the west can work normal, Maybe I miss some setting flow in 0.7.2?

#6858

Hi,

Hope you all are doing well. I am now doing the Zephyr Example

zephyrproject/zephyr/samples/boards/nrf/mesh/onoff-app

I am flashing this example on nRF52840_10056 DK. The code is building and flashing into the DK but it is not showing any output like when i press the Button 1 the LED 1 does not switch on. I tried flashing many times.

Note: DKs buttons are functioning as i have tried with BASIC example given in Zephyr Samples.

Please advise.

Thank you

Muhammad.

Subject: Re: [Zephyr-devel] ILI9340 Display Example

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Is there a way to disable/enable one of two composite usb protocols at runtime?

Li, Jun R

#6855

Hey Zephyr’s USB experts,

I’m trying to use a setting variable to disable / enable one of two composite USB protocols instead of static configuration during complication. Is there a way to achieve that? Thank you!

Regards,

Jun

Hi there,

export ZEPHYR_TOOLCHAIN_VARIANT=zephyr
export ZEPHYR_SDK_INSTALL_DIR=/home/swapna/Documents/Workspace/Zephyr_ESP

Is the SDK installed in /home/swapna/Documents/Workspace/Zephyr_ESP?

export ZEPHYR_TOOLCHAIN_VARIANT=cross-compile
export CROSS_COMPILE=/usr/bin/arm-none-eabi-

You cannot build an Xtensa target with an Arm compiler.

Hi Muhammad,

Could you switch to latest master and test with samples/drivers/display, for me that sample is working with the same adafruit display?

Keep in mind that in case you have a preview development kit of the nrf52840_pca10056 you will need an extra patch:

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Subject: [Zephyr-devel] API meeting next week: Focusing on watchdogs

Hi all,

Next week (Tuesday 10th of March) we will focus our attention to
watchdog handling in Zephyr.

We recently closed #22858 with the merge of #22859, but this was a
temporary solution to what is ultimately a wider problem that requires
a discussion regarding the way Zephyr manages watchdogs in general.

A good description of the current issues with the
CONFIG_WDT_DISABLE_AT_BOOT option can be found in #22858.

During the call we will discuss the approach we want to take and
document it in #23282, which I just created today.

Zephyr 2.2 released

Johan Hedberg

#6846

Hi,

We are excited to announce the release of Zephyr RTOS version 2.2.0!
 
Major enhancements with this release include (but are not limited to):

* We added initial support for 64-bit ARMv8-A architecture (Experimental).
* CANopen protocol support through 3rd party CANopenNode stack
* LoRa support was added through integration of the Semtech LoRaWAN endpoint
  stack and addition of a new SX1276 LoRa modem driver.

The detailed release notes can be found here:

https://github.com/zephyrproject-rtos/zephyr/releases/tag/zephyr-v2.2.0

I would like to thank the community members who contributed to this release. There were a total of 2642 commits from 205 contributors in the development of 2.2. It has taken a lot of hard work from everyone in the Zephyr community!

Starting now, the tree is open for new features targeting the 2.3 release, which is tentatively scheduled for May 29th 2020.

Thanks again,

Johan

Hi Muhammad,

Could you switch to latest master and test with samples/drivers/display, for me that sample is working with the same adafruit display?

Keep in mind that in case you have a preview development kit of the nrf52840_pca10056 you will need an extra patch:

Dear Mr Jan,

Thank you very much for your help. The problem is resolved until the program Building. Now when I west flash, it runs but I am not getting any output on the screen. I am using the following Ada Fruit version.

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Jan

Dear All,

I hope you all are doing well.

I am trying an example in

zephyrproject/zephyr/sample/display/ili9340

The example is building fine with nucleo board

west build -b nucleo_l476rg .

BUT

Please advise on the following error when building with nrf52840 west build -b nrf52840_pca10056 .
