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...
Hi.

Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
The problem is exactly same with the topic. I have custom board for Beacon. At the beginning I soldered 5 boards and all of them was working perfectly. After few days, 4 of...
One of the features of our product is the ability for a user to rename their device. I have tried to implement this with the sd_ble_gap_device_name_set(...) and ble_advertising_restart_without_whitelist...
Hi,
Would it be possible to change this setting (Relay) dynamically, i.e., instead of changing the value of m_relay_enable in the network_init() function and program the...
I'm using this code to log the BLE MAC address on my peripheral device, an nRF51822.
void ble_log_mac_address(void)
{
// Log our BLE address (6 bytes).
ble_gap_addr_t...
Hi,
I'm basing my project on ble_hrs_freertos example project (nRF52832, SDK14.2, PCA10040)
When calling assert(condition) in the original example project, it works...
Hi!
We are evaluating the 52832 soc for use with a DALI-controller. The communication speed with the controller is at 1200 baud, Manchester encoded. Is it possible to interface...
In BLE communication, I want to send 244 bytes of data from the peripheral to the central every 50 ms, is it possible? If possible, please tell me the setting method.
Hello, I have a problem with the configuration of GPIOTE low accuracy pin interrupts. My code is running on nRF52832 and already uses ble stack, PWM1 and PWM2 instances with...
Hi,
Right now I have a program on nRF52-DK (SDK 11) that scans for BLE adv packets, and transfers data from some specific addresses to PC through UART. Around every 10ms...
I'm attempting to use the PPK with the nRF52840 PDK with no success. I'm getting nothing running the nRF Connect with the Power Profiler. Configuration is as follows:
nRF52840...
Hey Guys,
Have been playing around with various MTU sizes to better understand throughput. I'm curious about one scenario though. Let's say for example that we are using...
Hi
We are using a slightly modified (but fully compatible signed bootloader) in out product. On the application side we have a C# implementation of the DFU protocol that...
Hello there,
In my next project I need a data link similar to BLE classic (like the HC-05 module) and it needs to respond with an app API fast and push data rather then...
Hi,
I'm following "ble_app_uart_c" example and works very well with SDK 10.0.0. So now I want to communicate with HM-10 module, but this has one Tx/Rx Characteristic. Are...
Hello,
In my quest to monitor the activity of hundreds of nodes (directly addressable), I am facing quite an obstacle.
The small memory of the nrf52 (nice piece of hardware...
