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...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
I am building a WSN has several peripherals (custom nRF51822) and one central device (PCA10031 in serialisation connected to a PC and using the nrf51-ble-driver_win_0.4.0...
It seems to be a straightforward BLE app but I cannot make it work.
I start fresh from the “ble_app_template” in nRF51 SDK 8.0.0, and try to add two service data (battery...
I want to give my own custom characteristics fully unique UUIDs, but am unsure how to generate those.
Is there a procedure to generate a custom, vendor-specific base UUID...
Hello,
I'm developing on a nrf51822 with the S110 softdevice.
To save power, I use the sd_app_evt_wait() function to go into sleep mode.
To wake up, i want to use an...
Hi all,
I developed a program that works fine on the dongle. The dongle has a chip with product code: N51822 QFAAG0 1342AA. When I upload the program including the correct...
I'm using s110 softdevice 6.1 SDK. I do bonding in my application the same way as in the ble_app_hrs example (bond, no_mitm). I have a charactarestic set to SEC_MODE_SET_ENC_NO_MITM...
my chip is nrf51822,I used s110-sd-v7, it's work. I switched the software to s110-sd-v8, GPIO interrupt is high priority (APP_IRQ_PRIORITY_HIGH). I erase the flash (pstorage_raw_clear...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
For a new product design with the nRF51822-QFAC rev3, could you give me the matching baluns ? Just the Johanson ?
Presently Stmicroelectronics told me that the BALF-NRF01E3...
Hi Sir:
I written below code according to example code.
In timeslot, rng will start with "rng_start_bv ".
Then the process will wait until "rng_ready"==1.
But, it can...
Hi,
I'm trying to implement a pulse counter, and send the data to client via BLE. I have debugged the module of the counter without connection separately, it's working...
The ' Downloads ' tab at www.nordicsemi.com/.../nRF51822-Evaluation-Kit gives only the v2.0 Hardware Files.
I have the older v1.0 board - it isn't quite the same!
Where...
