I'm using the RSCS demo as the peripheral and the Relay demo as the central. I've modified each to use stored bond information if it is found in flash upon startup. I make sure they are connected and bonded, then I reset each board. Looking at Debug output…

I saw in some post smart Bluetooth can have 7 active device. I would like to know what is the maximum number of Bluetooth devices i can pair up in sleep mode? i am doing a project which needs at least 150 Bluetooth devices to be paired up.

HI sd_ble_gap_adv_start() is returning INVALID_PARAM when it's being calling in ble_advertising.c I have read through the documentation and I don't see anything incorrect. Furthermore, both arguments (adv_params and m_conn_cfg_tag) are identical to…

I am trying to pass data to a central device by updating a characteristic. I am calling the function sd_ble_gatts_hvx(m_bcs->conn_handle, &hvx_params) after passing a hvx_params.p_data to the data of size 17. When I read it on the central device it is…

Hi, I am using nrf52832 for my application. The application share same SPI module for two sensors(with sensors are selected using two chip select pins). Is it possible to implement PPI channel between a timer and this SPI module so that I can collect…

I am new to Nordic, and Keil, and not especially strong in microprocessors yet. I am trying to get currently developed firmware for a nRF52382 chip to operate on a custom built board. I submitted the following problem to the rest of my team, but I…

HI dear: We have two questions to ask you： 1、Can we customize two different BASE_UUID in the nrf52832 ? If we can,and how to do it,We can customize one BASE_UUID (128bit),but can't customize two. 2、How can we operate the ADC in the Bluetooth protocol…

Hi, I was checking out the forum and I read that its possible to start a timer from the handler of another timer. However it doesnt work for me. Im using S132 v2.0.0 Any ideas? main.c APP_TIMER_DEF(app_tmr_id); int main(void) { NRF_CLOCK…

What is "1 Mbps Bluetooth low energy mode" for nRF52832? How was the spec. changed from my old year 2013 understanding that BLE is low speed for sensor, sending tens of bytes on coil cell for 1 year. The older BT2 and BT3 support higher speed data…

Hi Nordic Tech support team, I'm Hardware design engineer and working on wearable IoT design and would like to implement OTA programming for nRF52832 Bluetooth SoC.Kindly support me for below my queries... 1)Do we need any hardware design change…

I am trying to probe sysclk signal on one of the unused GPIO pins on a nRF52 board. I modified the ble_app_template example provided in SDK 11.0.0 and added a sysclk function to see the sysclk signal on P0.11. The project builds and loads with no errors…

Hi, I just got a nrf52832 pca10040 board and I downloaded the last SDK nRF5 v11. I downloaded Keil uVision5 and was able to load some examples and test them: nfc record_url, blinky_freertos... I want to use BLE capabilities of the chip (not ANT)…

I need a clock output (> 12MHz) from nRF52 for interfacing a sensor. From the below post, looks like Max possible output is 8MHz since peripheral clock is limited to 16MHz. devzone.nordicsemi.com/.../ Can I enable ETM and get 16MHz from TRACECLK…

Hi, I'm trying to get a custom PCB working. I can use either the plain peripheral UART, or the ble-app-uart example projects on the NRF52-DK and they work, but they don't on my custom board. I'm using different pins for RX and TX and I've changed them…

Hi, I need to wait for a period of 7.5ms whilst my I2C sensor completes a measurement, I am currently using the nrf_delay_ms function however I am looking to optimise the current consumption of my device and the ~5mA current consumption during this…

Hello guys, I have a very strange issue when working with UICR 's customer register. I am using a SEGGER Flasher Portable with J-Flash V5.10d to load a hex file (which is a merged from the SoftDevice s132 v2.0.0 and my DFU Bootloader) on our boards…

Hei guys, for a new custom board based on nrf52832 where i have to minimize power: have an external Li-Po battery, with a cutoff @3.0v, so the range will be 4.2v-3.0v want to bring Vdd to fixed 1.8v via an external DCDC ( it will supply power…

Hi! We are using ble_radio_notification for changing the advertisement data after every advertisement. The problem is that it doesn't work, the device freezes when trying to do this. Here are some code snippets that might give you a better understanding…

Hi, I'm trying to implement a HID gamepad on nRF52832. Here is my situation: nRF is receiving frame over UART from master uC every 15 ms. Frame is being converted and sent as input report (9 bytes). Gamepad would also support feedback. While testing…

I am trying to run BLE central peripheral dual role on nrf52 pca10040 with nrf_uart as service. Also, I have redbearlab BLE nano as peripheral (nrf51822 based). I am getting device manager's DM_EVT_CONNECTION event but after that I don't receive any…

I'm looking at log_uart_init in the nRF5_SDK_11.0.0-2.alpha and wondering if it would make more sense to allow the application writer to pass in a baud rate.

Hello, There are two problems on nRF52 ble uart example code. I would like to know is there any misunderstanding or mistake I made? or anyone met the problem too. 1. I used the example code of ble uart (ver:nRF52_SDK_0.9.2_dbc28c9) with S132(v1…

I'm trying to figure out something I'm seeing. I've modified the relay demo in the nRF52 SDK so that when I press button 2 on the board, it destroys any connections, erases bond information and begins scanning. Is it a no-no to do these three things…

Is there any reason I could not modify this demo to use IRK values and allow whitelist scanning based on stored IRK values? I'm wondering why the demo seems to have an option to use a whitelist, but never changes m_scan_mode to turn it on? Also, it is…

Hi, I'm new with a) the Nordic Softdevice environment and b) using the nRF52. So there are a few questions... As a starting point I've used the template project (...\SDK\nRF52_SDK_0.9.2_dbc28c9\examples\ble_peripheral\ble_app_template) and added…
