Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...
I use a app_timer_create() function to create a task(200ms once)
when in the task_timeout_handle() ,
I do something more than 200ms,
what will this timer going ?
Hi!
I use nrf51-pwm-library ( github.com/.../) to control brightness of LED RGB light source and it works ok till I don't want to adjust brightness slowly (dimming function...
We highly anticipate it will but wanted to ask here before we might ask Nordic Support to confirm that the nRF52840 will make use of the ARM TrustZone CryptoCell to provide...
I'm looking to design power management circuit for a 3.7V Li rechargeable battery powered wearable sensor design. Any such reference design would be greatly helpful!
Thank...
I'm developing a device that's supposed to establish an encrypted connection with an Android device and I've gotten PM_CONN_SEC_ERROR_PIN_OR_KEY_MISSING during connecting...
I have the Type 4 Tag sample application running and I can read and write the tag without any problems.
I'm getting a little confused reading through the sample application...
Hello,
I am working with the GPIO tasks and events feature on my nRF52832 DK. And I noticed some strange behaviour. I want that two Pins will toggle if some timer events...
Hi,
Please help me with the following theoretical situation:
I have a NRF52832 running HID profile, mostly sleeping.
From time to time, an external interrupt occur (GPIO...
Hi,
I am trying to get the data written from a central (a smartphone in my case) to one of the characteristic of my peripheral using write request. The problem is that...
Dear developers,
We had a working application with SDK11 SD2.0.1 that we have migrated to SDK12 SD3.0.0. With SDK11 we could successfully bond to multiple peripherals and...
Hi. I use the nRF51882 and Arduino ide for developing. My main goal is turn on and off the Led thru the Bluetooth interface. But when I use the UART service for it I have...
I am seemingly haunted by spurious 'soft resets' I cannot seem to find a good explanation.
I have an application that is to be dormant until activated. When waking up I...
Hi, I'm a newbie to Nordic and need to use multiple nRF24LE1s to get ADC values and transmit them to a single nRF24L01 connected to an Arduino. I need sample Keil compiler...
Hi, Nordic
I download SDK13.0.0-1.alpha_055eef3, open project

Is there any example of changing the default mtu size of 23 to a bigger value?
We tried increasing the att_mtu to 512, and reserved more ram for the softdevice, but still...
I have a rather unique problem. I want to control an "old-fashioned" DPDT relay using nRF52 GPIO lines. I'm trying to accomplish this task without adding a power transistor...
