We will get a beacon from China. But how do we know if the chip is original? If I can read the unique device id, can I say it is original? Or is there another way?

Hi, I'm trying using AES ECB encryption of peripheral drivers on development board with nRF52832 and PCA10040. I inserted the following code before main loop of ble_app_uart sample in nRF5 SDK version 12.2. #define SRC ((uint8_t *)"sample 16B…

I am using various sensors to build a wireless sensor network. There are libraries for sensors that are provided by developers such as from adafruit or sparkfun. I have been using them in arduino with adafruit's nRF52 Bluefruit to simplify the testing…

Hi, I'm trying to set up my SAADC to measure VDD and battery voltage on AIN3. According to this post , later versions of the SDK were modified so that one could use scan, burst, and oversample. But I'm using 14.1, and it seems like nrf_drv_saadc_channel_init…

Hi, I'm currently in the process of integrating unit testing into our firmware development process. I'm trying to execute on-target tests with the Unity test framework, using the Nordic-modified version provided in this post. This has been working…

I'm concerned about users writing too much or invalid NDEF data to the NFC function. This could result in parse errors or buffer overflows leading to system crashes/malfunction. Since the t4t_lib is closed source, by any chance, are these conditions…

I am having a strange issue with the serial DFU in SDK 11, s132v2, specifically running either dfu_dual_bank_serial or dfu_single_bank_serial. My goal is to simply get the demo up and running, but I seem to get stuck when the bootloader tries to jump…

Hai i am new embedded designer.. I am working with nrf52832 , i need to get accelerometer and gyroscope data from mpu6050 through twi.. Can any one give me a sample code ? Please help me

Hi I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52. Both the reference resistor and the PT-100 is sampled while the voltage divider isn't connected to Vcc and while it is (using a PMOS transistor). …

HI,all when i want to notify with MITM,there is an issue with my project. my central role device is IPHONE and the app is lightblue . When i enabel notify ,the nrf52382 restart. i know now the reason is the statement ' BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM…

HI,ALL there are two 'uart_event_handler' function in the project. one in main, and the another in the app_uart_fifo.c with the source code, i think when i input a character through uart, the 'uart_event_handler' in the app_uart_fifo.c call first…
