Hi, I have an nRF5340 Audio DK. As the first step, I want to play a simple 1k Hz tone and output it via the AUX jack on the board. Is there any related sample code for me to get started with? Alternatively, I do have an external DAC module that takes in I2S data. Is there any example code that demonstrate how to use I2S feature in nRF Connect SDK? Thank you!

Hi, I am writing to seek guidance regarding the implementation of Modbus communication on the nRF9160 Development Kit. As a developer who is relatively new to the concept of Modbus, I have been exploring the capabilities of the nRF9160 board and have come across sample code for Modbus RTU client and server implementations. However, I have some queries regarding the feasibility of using this functionality on my current setup. Currently, I have only one nRF9160 Development Kit available for testing purposes. My primary objective is to perform both client and server operations using this single board without the need for additional hardware. Is it possible to perform both client and server operations with just one nRF9160 board? Can I utilize the UART TTL interface on the nRF9160 board for Modbus communication? Given my setup, where I intend to use a computer as the master and the nRF9160 as the client,

Hello, I am currently using some code from the HTTP client sample to send HTTP requests to a server from my application. I have encountered an issue where the thread from which I send the request occasionally blocks. The serial log indicates that the execution stops at the getaddrinfo function and hangs indefinitely. I have left it running for up to 20 minutes before resetting, but getaddrinfo did not return. This issue occurs randomly, sometimes minutes after booting, and sometimes after hours of sending data to the server. Other threads (like the LCD) are working fine and remain responsive during this time. Here are the details of my setup: Module: Avnet AVT9152 SoC: nRF9160 SDK: nRF Connect SDK v2.5 Modem Firmware: Latest version Here is the function I use for HTTP requests: int http_client_send_request(struct http_request *request) { int err; int fd; struct addrinfo *res; struct addrinfo hints = { .ai_family

Hi I am facing this issue were I need but 1v8 and 3v3 at the same time to power PPG sensor and it's LEDs so if there any example code for this approach pls share. Best regards Karthik

Hello, I am a beginner with the Nordic development kits. I have purchased two nRF52833 development kits and I would like to perform Bluetooth Direction Finding with these kits. Before that, I would first like to implement periodic advertising of BLE packets to understand what happens before I jump into direction finding. I have seen that periodic_adv and periodic_sync are two examples that I can run to understand their working. The periodic_adv sends periodic advertising data every 10 seconds as given in the sample. But I am unable to receive the packets in the periodic_sync. I have not made any changes to the sample code. I would like to know what I am missing out and maybe some guidance on how I can send different data in place of the mfg_data[]. I have attached the serial monitor log for both the periodic_adv and periodic_sync. Periodic_adv: Periodic_sync: Here, it does not

Hello, I am trying to established a Bluetooth communication between nrf52840dk and Fanstel BLG840F. nrf52840dk acts as peripheral device and Fanstel BLG840F acts as central device. For peripheral device, I am using ble_peripheral -> ble_app_uart example from nRF5_SDK_17. For central device, I am using bluetooth -> central_uart example from nRF SDK Connect. I am sending some dummy data from peripheral to central. But, I am stuck on pairing which is constantly failing if I use security. I get below error. And if I remove the below security, the I can see the peripheral device led stops blinking. And, on central side terminal window, I can verify it getting disconnected but, I didn't receive any data on central side. I am guessing this is because ble_data_received() is not getting executed (as I have given a print statement which is not printed on the central terminal). err = bt_conn_set_security(conn, BT_SECURITY_L1); if (err)

Hello Team, I am using nrf52840 board which supports ZIGBEE and ZEPHYR. Setup Details: Zigbee_LIGHT_BULB (nRF52840 DK) Zephyr_BLE_CENTRAL (nRF52840 DK) In zephyr I have implemented BLE CENTRAL CODE and in ZIGBEE, LIGHT_SWITCH(ROUTER) and LIGHT_BULB(END_DEVICE) examples. Now, I want to control ZIGBEE LIGHT_BULB(END_DEVICE) to turn ON and OFF the BULB using BLE CENTRAL CODE. 1. Is it possible to control ZIGBEE LIGHT_BULB(END_DEVICE) using BLE CENTRAL CODE in ZEPHYR which is implemented in zephyr? 2. Also, In ZIGBEE LIBRARIES, why ZEPHYR BLE CENTRAL CODE is not supporting ? As I am new to this, please help here get the above information. Thanks a lot !!! Best Regards, Deepika B

I have a nRF9160DK board running asset_tracker_v2 on a nRF9160 custom board. V1.7.0 loads and boots fine but when I use V2.5.0 the boot fails as shown below. The only change I have made to the V2.5.0 asset_tracker_v2 code was to change the 2 lines in prj.conf that had my AWS information. This code loads fine in a nrf9160DK board but fails when I use the V2.5.0 version in the custom board. The V1.7.0 version loads in the custom board and had been running for several years. any ideas what I am doing wrong? any way to get more information on why the boot is failing? any help would be greatly appreciated. We have V1.7.0 out in the filed in many sites for years and it is working perfectly. The decision was made to upgrade to V2.5.0 so I am stuck until I can get this to boot correctly. I

Hi Community! I am a beginner with NRF and zephyr and currently doing a small project on nrf52832_mdk on zephyr. I want to deep sleep the system (sys_poweroff) when nothing is happening. I followed the poweroff example and its working fine. I have attached a multimeter in paralell to measure current and I can see the current drop when system poweroff smootly. In my actual project, when I run the sys_poweroff command in main thread after initialization, it gives the expected results. The system shuts down completely and current drops in micro amperes. int main(void) { printk("initializing the system \n"); int ret; int errorCode = 0; struct sensor_value regValue; /**** Initialize LED****/ ret = led_init(); if (ret != 0) { printk("could not Initialize LED \n"); } /**** Initialize the SC7A20 Sensor ****/ ret = sc7a20_sensor_init(); if (ret != 0) { printk("sensor Initialization failed \n"); errorCode = ERROR_SC7A20_SENSOR; } ret =

Hey, I watched webinar with presentation of NDT and a Lidar as a reference data and if looks quite impressive for high precision calc method. We are using 7002 DK and we would like to really see how it works. Currently we did some testing for IFFT method from nrf-sdk samples, but as it was said in webinar these result are not trustworthy for wide measurement ranges. However, i haven't seen example usage of nrf_dm_high_precision_calc() function in sdk, or github. I know that there is a need of calling nrf_dm_populate_report but i still fail using this with sdk 2.5.0. Could you maybe share a piece of code, where you present how to properly use these tools for high precision distance measurement? It could be for other target or SDK version, i just need a start point.It could be the code, that you use for webinar measurement with roll camera :)
