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...
Hello,
I am using UART_1 in my program to comminicate with other sensor. So the data is read from UART_1 and print to UART_0. Now I want to communicate with other sensor...
Hi, I am using BMD301 chip on my custom board which schematic i have shown below,I need to enable UART as well as nrf_log in my application. For this I am using SDK 15.3 PCA10040...
I am getting small power spikes but cant seem to pinpoint what is causing them.
The smaller spikes in between the transmissions. (The wave is clipped from the top so the...
Hello,
Has there been any success with getting the python bindings for the pc-ble-driver running on openwrt? I've succeeded with the driver itself but not the bindings....
So with the errata in mind the RC oscillator has a accuracy of +/-500 ppm, while the XTAL on the nRF52 DK has a accuracy of +/-20 ppm. During the longest waiting period of...
I have your full eval board as well, I also have multiple NB_IoT sims from Vodafone but have not tried them yet. How do I get your Thingy:91 unit with your sim running please...
Hello,
I want to implement a data logger that will save events in an external flash (even if i think i will start with the FDS). My purpose is to identify some behavior...
Hello,
I am looking to start an independent project this month. One of the tasks will be to use BLE to relay information from a custom PCB board with the nRF52810 chip...

The power consumption immediately going up high to 1MAH once I enable TWI using this code:
NRF_TWI0->ENABLE = TWI_ENABLE_ENABLE_Enabled << TWI_ENABLE_ENABLE_Pos;...
Hello,
When I added the below lines I get some error:
NRF_BLE_GQ_DEF(m_ble_gatt_queue, /**< BLE GATT Queue instance. */ NRF_SDH_BLE_CENTRAL_LINK_COUNT, NRF_BLE_GQ_QUEUE_SIZE...
Hello,
I have been looking through Nordic's documentation for the nRF9160 and trying to find voltage ranges for several pins but am having no luck. Can someone please answer...
iOS is using queued writes to send data to my nRF52832 application. For some reason, on the third queued write reply (in nrf_ble_qwr.c) sd_ble_gatts_rw_authorize_reply returns...
I'd like to build a prototype using the nrf9160DK that samples audio from a microphone and plays it back. Given that the dev board has Arduino compatible headers, I'm assuming...
