why use 50ms and 400ms connection interval for testing the maximum data throughput(2M,247byte payload)?
Because 50ms can only send a pdu , and 400ms can send up to 8 pdu...
Hi,
I am using Keil IDE to develop nRF51822 project.
in main(), the command line

Hello,
I'm new to the Nordic SDK and I would like to ask you for help with implementation of PORT events for revision < 3 in "low power" mode instead of "high power" mode...
Hi Nordic,
I've built a ble app with a custom protocol, but am struggling with storing bonds, when running under freeRtos.
What I see:

Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
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

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...
Hi all,
there is a nice section in here already about enabling the Reset input (P0.21). Unfortunately the link to the relevant infocenter docu is missing.
Could you...
I think that all of the Experimental is all unreliable.
I try it 5 days to test it, It always Failure.
So , I want to know that to how to understand the keyword "Experimental...
Hello developers,
I am struggling badly to use interrupt in my application. I am using softdevice S130 and ble_nus, ble_bas and ble_hrm services. All I want is to trigger...
