At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
Hello everyone,
I got a task which I try to implement using a NRF51822 iBeacon board.
The Task:
Advertise a Device and provide a mechanism to connect without traditional...
I created a simple message mode based on the simple_on_off modle,when I debuged the codes in simple message client,I got an error(app_error),I never changed the codes for...
hello,
I used NRF52832 as a ble gatway.Now i have a trouble that the received signal strength is jumping about 2dBm when the chip loaded program.I test it with Spectrum Analyzer...
Hello! I am trying to prototype a DFU solution that works well for our application. We want to build a network with both normal Mesh devices and with friend nodes (once that...
Hi,
for my PCB, i'm using an NRF52832 as SPI slave, i send an array of 4 bytes {0xA5,0x00,0x01,ff}, but my SPI master receives always a byte (0xff) before 0xA5.
this...
Hello everyone
I have kind of a basic question.
I'm not sure how to manually disconnect from a ble connection. I'm using the ble_app_uart and ble_app_uart_c examples from...
Hey all,
We’re trying to figure out the best way of keeping our nRF52 (or 51) based design in the lowest power mode possible while sitting in inventory.
Currently, our...
Greetings,
I have 12 sensors each of which is located on an nRF52832 board. I need to collect the sensor data at 50Hz (10 bytes for each sensor).
For some reason I can...
This one is throwing me for a loop.
We just did a small build of 40 devices based around the nRF52832. 1 device out of those 40 is behaving very strangely. When the device...
Hi Sir
I want change the power transmission level for measuring the RSSI values for different configuration from -40DB to 4DB. for that i configure the radio. But it is...
When compiling (after the project folder change and paths updating) I get always this error.
No idea why. The C99 option is choose
It compiles correctly from SDK tree...
Hello,
I just finished migrating my project from SDK13.1 to 15.0. It caught my attention that when I flash the Softdevice, it uses memory from pages 0x00000 - 0x24000. I...
I think I found a bug in nrf_ringbuf_cpy_get. The first memcpy is wrong. The source and destination should be swapped.
if (length > trail) { memcpy(&p_ringbuf->p_buffer...
Hello,
I am using the NRF51822 in a low power application and need to transfer the data from the PCB (with the NRF) to the PC over Bluetooth. I need the biggest possible...
Hi,
I would like to know if there is any reason that tx_power is limited to +4dBm in the Mesh examples. I am using an nrf52840 and it is capable of +8dBm. Would it increase...
