First time here? Check out the Tour!
Hello the Nordic Team,
I come here after a lot of research and testing and do not understand what is going on in my program. (is it Embedded or iPhone nRF Toolbox side ?)
I took the ANCS code ( nRF5_SDK_12.2 ... (more)
Hi. When i
use ble_app_uart i have problem with my device over uart. It does not response to my commands.
I'm using custom pcb based on
nrf UART v2.0 android app.
Is there something i'm missing?
Is only a single async UART supported on the NrF52 832/840 devices?
I wonder if someone can help me out. I would like to send serial data by modifying the 'simple_coap_server' main program. I added the following header 'app_uart.h' to make use of the functions but when I compile ... (more)
for some reason I cannot connect any PC terminal to my custom board: I would get consistent
NRF_UART0->ERRORSRC = 0x000c or
0x0004 indicating break and/or framing issue. I hope someone has any hints to help me out ...

I'm using the NRF51422 with hardware UART. Brief outline of the configuration: 115200 Baud, 8-N-1, no HW flowcontrol SoftDevice S130 V2.0.1 lib: app uart fifo
The main problem seems to be the SoC trying to send ... (more)
I can't get NRF_LOG working with SDK12.3.0. Using the same main.c and sdk_config.h from SDK12.2 - here NRF_LOG is working well - I get no messages in J-Link RTT Viewer with SDK12.3.0. ANY hints ... (more)
Hi, i am using this program to send the data captured on 3 sensors from AIN0,1,2 to the mobile nrf toolbox application via BLE UART.
The problem is that when the sampling of event starts, it only sends ... (more)
I have a custom nrf52832 board. I have changed the UART TX and RX pins to P0.3 and P0.4 respectively. If the pins are floating, then nrf52832 stops advertising,If something connected then there is no issue. Do ... (more)
hello,i am using nrf52 dk, & am working on bluetooth uart & looking for data is send from mobile to nrf52 dk board. i am having examples of data is sending from board to mobile nrf Tool app. But i want ... (more)
I am using a bootloader based on the secure serial DFU bootloader example in SDK 13 and tested it on a development kit. I noticed that hardware flow control is enabled in both the bootloader code and the nrfutil Python ... (more)
I've been having a little bit of an issue trying to parse UART data that I am receiving from an external device.
Where I'm having issues right now is comparing an incoming byte with a specific character. I ... (more)
Toggling a gpio pin upon receiving a particular string from ble uart app
I need to receive both UART Service data and HRS service data on the app.
Currently I have seen on Nordik Connect app , both the services can be found and can connect and receive data.
I need to do same ... (more)
This is obviously not the first question about this, but I still haven't found the answer I need here...
I would like to make a kind of serial to BLE gateway on my PC. I mean I would ... (more)
I feel like this question has an answer similar to this question, but I can't seem to get it working https://devzone.nordicsemi.com/questi...
I am using the nrf51422 chip on a board I designed myself and ... (more)
Firstly, platform: Sparkfun 52832 breakout board, DFU using UART, flashing an application, using nrfutil.
The problem fundamentally is the nRF52832 is not sending an ack that it received the DFU start packet. The packet is formatted correctly as defined by ... (more)
I'm trying to implement send && recieve through one wire. Handling of pin state, if it is input or output is done via SW. Also it is going to be half-duplex only.
Is it possible to do something like this ... (more)
I modified the gatt_init code in SDK13 to support the largest ... (more)
I am using a nrf52832 to communicate via UART to a GSM module (AT commands).
I have setup the device with a baud rate of 9600 and using HW flowcontrol. The nrf52 is doing other stuff at the same time ... (more)
I'm developing a project based on the Nordik UART Service and I wouldn't use pairing as in the example.
However I have some problem when a central device is already connected to my nRF52, if I try to ... (more)
if I use softdevice 130 Enabled, then do I have any restriction with using all of the pinout of NRF51xxx?
Or if I use Nrf-51 DK, Do I have any restriction with nrf 51xxx's full pinout functionality?
To Make ... (more)
Hi, i'm working a BLE gateway with NRF52DK and S132 by using the demo example central uart.
The peripheral equipement advertise manufacturer data like this: 0x0001 during 5sec then 0x0002 during 5 sec and stop advertise.
But I want ... (more)
hi i flashed s110 softdevice 7.1.0 then ble_app_beacon example application fron sdk 7.1.0 into nrf51822 beacon successfully.but led is not at all blinking in beacon.and i can not detect that in nrf uart app.
Q0. What IRQ Priority does BLE Has? and also what IRQ Priority does UART can have?
I'm guessing that from s130's document P65, Exception Model, It says,
Softdevice Timing Critical has Cortex M0 priority 0,
Application Interrupt priority ... (more)
I am trying to use the function or any function with my BLE UART application. I have a timer that expires to kickoff reading of some sensors and then when I try to read my sensor it only writes the ... (more)
I want to be able to read my i2c and program logic flow within the BLE application but when I try to set breakpoints it causes the cpu to do a hard reset. How can I capture the assert condition ... (more)
I have multiple PCA10040 boards, and about a year's worth of experience developing code for them. I have suddenly started to have problems with USB-UART connections. Not even Nordic's SDK example code (in ../examples/peripheral/uart ... (more)
I have an nRF51822-DK board and so far I could not properly grab from the examples a simple thing: is there any specific initialization needed when coding?
For example I currently run APP_TIMER_INIT, APP_UART_FIFO_INIT, etc. but should I call some ... (more)
As a small team, we have to find silicons from retell market. Sometimes even the trader can not promise its source and batch. Here is a small list of nRF51822 available from the market.
