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 everyone,
I have 2 chip; Bluegiga and nRF51-DK
I can easily advertise my custom service in Bluegiga chip. As you can see, nRF Connect application shows my service...
I think one way or the other the struct ble_gatts_evt_t must be correlated with the GATT profile, that is, ble_gatts_evt_t should have services and characteristics as its...
Hi,
> Context:
I run a baremetal application that I would like to enhance with bluetooth.
I am considering a BLE module from NS.
I currently have a SoC (nanopi...
I have created a nRF52 based peripheral device which is used to stream sensor data to a connected central device, usually an iPhone. I can stream data, reliably to the iPhone...
I have an odd situation. I've been using an iPhone 5 and 6 to connect to, and test against, both an nRF51 (redbear nano) and the same code built for nRF52. It works fine....
Hi All,
i am using nrf51822 with SDK 12 and i am not able to find where All BAUDRATE Macro is defined for APP_UART.
so anyone can tell about that in which file it is...
I looked at examples and added identical code to my own app, specifically to a) set the gatt_enable_params.att_mtu to GATT_MTU_SIZE_DEFAULT, and b) to handle BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST...
Hi,
Is there an extensive documentation about programming process of a nrf52832 using keil?
I just spent hours figuring out that I had to use Softdevice erase flash algorithm...
I just followed "Testing the example manually (without bonding)" steps to manually update firmware by Master Control Panel.
But every time, I got log message, "SERVER:...
I am implementing mqtt client on Nrf52832 with the example provided in the IoT SDK. I am looking for the correct way to make the client to run with Non-Nordic socket stack...
I've just finished my first layout for nRF51822, and I need a help with the attenna design.
The RF part of the schematic and layout is a copy of your reference design, "PCA10004...
Hi
I'm using BLE400 board (from waveshare) which have a nrf51822 chip on it. When I want to program the softdevice with nrfgo I encounter the following error:
