I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
This one is throwing me for a loop. We have a very basic NFC component in our firmware that serves up a static NDEF file and wakes the MCU from a system_off state.
We have...
Hi,
we are currently trying to implement an edge impulse model (keyword spotting, 600 ms window @ 16kHz) on a nRF52832.
The problem is that the SoC's RAM is already very...
Hello All,
I am programming an nrf52480 using zephyr on a windows machine.
I am trying to write a bluetooth peripheral characteristic, ore specifically to the led...
When using two nRF5340 Audio DKs as bis_transmitter and bis_receiver respectively for the iso_time_sync sample, the iso_recv event is triggered.
However, in the respective...
Hi,
I use nRF52805 chip for BLE tag. FACTOR_MODE pin will be used for production stage. At F/W start point, F/W reads FACTORY_MODE pin, if the pin is high, F/W will enter...
I am trying to program nrf5340 using this command: nrfjprog -f NRF53 --program merged_domains.hex --verify --recover -r
It works fine if readback protection is not enabled...
Everytime I make a call to the usb_dc_ep_write function I get error -22 meaning invalid argument. I have tried everything I can think of. I tried sending a blank packet with...
Hi:
My environment is: nRF5_SDK_17.1.0_ddde560, keil, s113_nrf52_7.2.0_softdevice When using the ble_app_uart example, "Failed receiving NUS message. Error 0x04. " appears...
After discovering that MBEDTLS requires at least 48000 bytes of heap to function, I've had to desperately find some spare bytes to conduct a TLS session over WiFi using a...
Hi,
We move from ESP32 to nRF5340. The API is different. I search all samples and I didn't get the correct samples. Anyone can show me which sample is suitable for us? ...
Hi, I want to use nRF52832 for a product. I am a bit confused about the package selection. I need QFN package but there are many different versions available. Can someone...
Hi,
we are working on a device based on a nrf52840 using zephyr 3.2, which uses bluetooth low energy for advertising and for providing some services with some characteristics...
Hello,
we are evaluating the distance measurement module to integrate an indoor location function to our product.
We see the module is still "Experimental".
We need...
Hello,
I have the peripheral BLE device. It is always had different mac addresses on disconnection/on reboot.
I use my mobile phone with Android OS to initiate pairing...
Hi, I need help with a simple example code to read analog pin 5 and either control brightness of the LED or print value on terminal. I found this example but it didn't work...
