Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hi,
I'm searching a way to create a function which would be a timer function (so, this function will have an int number as input parameter), and during this delay, I would...
On this question I read that S110 is blocking CPU a lot during advertising/connection ( devzone.nordicsemi.com/.../).
On this other question they say that you can change...
I am using two nrf51822 ek. one is programmed with multilink central and other is programmed with multilink peripheral. when i press the button on multilink peripheral, i...
I need to connect to a beacon with a scanner nRF51 using the advertising data of the beacon. Then i need to get the service and characteristics of the beacon.
Thanks
Hello everyone,
i am trying to compile the Ble-UART_example but everytime it shows this error 'GPIOTE_config_irq_priority is undefined ) and i dont know what went wrong...
I have tried to flash my application targeting nRF51822 on our board by using a Segger on nRF51 DK. However, Keil compiler always shows that it couldn't find any nRF51822...
Hi NORDIC
I have to complete a function that one can transmit and the other can receive . but I do not know how to set nrf51822 to be a receiver . please tell me or share...
Hi,
it seems that the default implementation of the ble_bas (battery service) provides the notification feature but not the "read" feature.
I client can enable notification...
I'm using the Github project github.com/.../nRF51-multi-role-conn-observer-advertiser in order to SCAN in a specific channel rather than all 3 channels. In this example, softdevice_handler...
Dear all,
Recently,i use nrf51422 trying to receive data from two ant sensor.
i assign two ant rx channels at the same time, i find i can't receive data if only one sensor...
We are planning to use a synchronous independent channel, that senses whether there are any slaves or not using acknowledged data type.
More than one slave could have paired...
HI,everyone!
I want to use pstorage to store some data, so I followed the steps given by devzone.nordicsemi.com/.../ , but it didn't work.
Then I checked ecah function...
Hi all,
I want to test power consumption of data packets reading from SPI to RAM using PPI.
But i'm not sure that can RAM act as a peripheral of PPI...
So, can i use...
I am using a solar powered energy harvested circuit to power the nrf51 module. However, when the generated voltage drops below 1.8v, the nrf51422 enters into brown out reset...
