Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
I am testing the IoT_lwip_MQTT_publisher_pca10056_s140 example project from SES on Windows.
I build and install the kernel with 6LoWPAN module on the Rpi3!
I can run from...
Hello，I'm from China。
At present, there is a need to broadcast beacon data in nrf51822 (SDK_12.3.0_d7731ad is used as the protocol stack version, and the...
Hi
I want to generate two PWM signals that are phase shifted with 90 degree, with similar duty cycle. I have the following pwm configuration, but I don't know how to proceed...
I am operating as a Central. How do I register and enable a discovered characteristic's indication?
I do the following and the subscribe passes but then the kernel crashes...
I'm planning to buy a nRF51822 based module for my BLE project & I wanted to know whether any of the nRF51822 based modules come with OTA ready bootloader out of the box....
Hi,
I'm trying to save sensor data to sd card on low power mode. When i connect to bluetooth mobile app can pull all data from sd card.
How can make this architecture...
Hi,
I'm using Nordic BLE Sniffer. When I look into the captured data I see a lot of malformed packet (CRC error). It try to decode any received data even if there is CRC...
I was digging around a bit in my code to get a better grip on logging. In sdk_config.h, I have the following relevant settings:
My modules all implement their own logging...
I am going to implement DFU over BLE in my nRF52832 project. Since the size of my application + softdevice larger than half my memory size I wonder how the update is performed...
We're looking to use the nRF91 to measure the LiPo battery voltage to determine battery health. We would want to know what the accuracy and range of %XVBAT is. Looking at...
I am trying to create CTS server using nRF 52840 dongle and nRF Connect PC app (v2.6.1). Currently I can manually provide current time and local time information to the app...
Hi, I try to adopt the twi_scanner example from the peripheral examples to the nRF52840 Dongle.
I followed the process in the following link with no success though.
https...
I'm trying to reduce the power consumption of my custom board with nrf52822.
With this code I get 93 uA:
If I enable only the app_timer I get 533 uA:
I'm using...
Hi
In a project with nRF52810 I use DMA of SPI and PWM to read data from flash and supply it directly to the pwm generator efficiently.
When reading from flash, I load...
