Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
Hi,
I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
This is not a real question for support. It's more a success story i'd like to share with you!
Our company develops firmware for various customers on a lot of different...
Hi all,
What is the maximum data rate for the nRF24AP2 when using the Synchronous serial interface?
I cann't see it in the datasheet.
Is there anyone can answer me...
Hi,
In my design, there is a tag used by 24l01,It can transmit the temperature value.In the tag, the parameters are like this:
addrofch[0] = 0xe7;
addrofch[1] =...
Hi,
I'm testing a BLED112 USB Dongle from Bluegiga ( www.bluegiga.com/.../).
I have not been able to use see the Nordic Board advertising. Currently testing ble_app_proximity...
I was wondering would it be possible to use a 50 ohm IC Antenna ( like this one ) for the nRF51822 with the matching circuit given for the nRF24 ( link here )?
It seems...
Hi,
Is there any difference(data rate) between sending large data packets through single characteristics and multiple characteristics?
I have created one characteristic...
Hi everone!
I need to get a timer setup which repeatly fires 2 IRQs. The first i.e. after a timer count cc0=500 and the 2nd count cc0=700. After 700 ticks the timer value...
Hi,
I've noticed that when using SPI without a Soft Device or BLE function calls, the SPI peripheral is easy to control and operates correctly.
This nice operation stops...
hi,everyone.
I try to use ble urat sample for bonding by passkey entry.
and connection established and to bond. i try to entry passkey by uart.
but when i key the passkey...
Hi!
Can you please recommend a LDO IC for a USB/Li-polymer Battery power for the nRf51822 please? The LDO needs to drive the nRf51822 and a couple of sensors such as Gyro...
I'm trying to get the ble_app_hrs example working in Eclipse, but the stack pointer is not setup correctly. It's at the start of the RAM (0x20000000), and therefore it already...
I'm implementing an Android 4.3 app which uses an nRF51822 and the BLE proximity profile. I have the following as starting points for the app code:
The BLE sample...
I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental...
Hi,
I have a C# app connecting to 51822 devices, doing data/firmware download. When I try to send erase page command (before write), erase works, but there is a disconnect;...
Should we keep track of this by monitoring the write events or poll the gatts value via the softdevice?
It looks like it's faster (+shorter = less consumption) to monitor...
