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...
Hi,
I just create simple example based on nRF51 ADC examples, using SDK12.3.0 with softdevice S130 v2.
I used PPI + Timer to get sample from ADC. I used TIMER2 to trigger...
Hi everyone and thanks in advance.
I'm new to the NRF52 SDK enviroment and I've been having some trouble with the I2C/TWI configuration. The SDK we are using in the v12...
Hi,
Is it possible to send notification periodically even if there is no change in the value? I create sample code that send constant value periodically over BLE, but in...
I'd like to use new nrfx drivers included in SDK 15. The problem is that I want to use C++ but nrfx header files are for C. The struct initializers can't be compiled as C...
I have a lot of pin_read function. How can i set all port one line? for example P1OUT = (P1.01 | P1.02 | P1.03) or P1IN = ( P1.01 | P1.02 | P1.03 ) I dont know how to use...
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...
