I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.
App flash base is set to 0x00021000 and app RAM base is set to 0x20003000
Looking at the CPU...
In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
Hello devzone...
My setup: nRF51422 and S110 peripheral
My setup transmits IR data on reception of Bluetooth data from a central device. I have used PWM for generating IR...
I bought 5 Seeed Micro Ble Modules. On their Website they answered a question 7months ago, that they ship with QFAA G0. I connected them via SWD with my nRF51-DK.
God damn...
I am trying to decrypt some data.
My data is encrypted using AES-ECB No padding method.
I know the 32Byte key used for decryption.
Following is the code snippet. I am not...
I guess and hope not but I am a little confused by the compatibility matrix..
I would need to use SDK 7 or higher for my nRF51-DK
but I would need to use SDK6.1 or lower...
Hi,
I searched here for a while and I couldn't find the answer. I implemented custom service by referencing nAN-36 and the github code. For some reasons, the github code...
Hi there,
I am trying to generate a pulse on a pin using RTC1 and PPI. Using a TIMER this works fine but my goal is to incur minimum current consumption by using only the...
I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
In the sensor datasheet it says one can use SPI_Mode 0 or 3 (doesn't say that there is anything to do to switch between them).
I connected MISO from the DK with SDO from...
I want my application to cooperate with DFU. I am using example DFU project from SDK (6.1) (from nrf6310 folder, i simplified it so it could work on PCA10000), but i need...
I increased my IRAM1 size as advised here , but now my program doesn't work anymore on the nRF51 DK.
I know the problem is somewhere in the memory allocation, because when...
I am working with nrf51422 chips version 2, so according to this table taken from the compatibility matrix v2.0, the last supported versions of SDK/SD/SDS I should refer to...
Also it seems not to advertise. What may cause this problem?
All I could found in the ble_gap.h is:
If both conn_sup_timeout and
max_conn_interval are specified...
Hi
I am trying to debug the "ble_app_hrs" example from SDK 6.1.0 (using keil IDE), on 51822 chip.
The IROM1 is defined to start at 0x16000 (meant to be used with softdevice...
I'm trying to minimize current consumption on my BLE peripheral and I wanted to know what advertising data is required. I have a custom service with a 128-bit UUID but do...
