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...
I'm trying to track down an intermittent bug in programming our Nordic board. So, I'm having to laboriously reconstruct the SWD transactions and understand them.
A transaction...
I use nRF51822 Model in my project that I need to run bluetooth advertising all time. And when I measured current, I found 1mA that is not enough to run for 1 year by just...
Hi,
My project include two MCU with n51822 and STM32. I expect upgrading STM32 application firmware by n51822 DFU function. Do you give your advice to implement it by modifying...
Hi All,
I am struggling getting my N548 module to transmit any ANT+ ...
I have tried the Cycling Power Sample Application (S310)
And the Cadense / Speed (S210) Sample...
Hello,
Is there any delay between when the reset pin is driven low and the actual reset of the chip. Would it be possible to sense the reset pin and perform some quick...
I am designing an nrf52 based device running at 1.8V. To debug the device I was planning to use debug out option of the nrf52 preview DK. However, I just find that, the debug...
I'm trying to follow the code from one of your examples, specifically ble_beacon in SDK 8.0 and eventually I get to a point where I'm not sure what's going on so I figured...
Hello,
I have question. I using examples with nRF51-ble-peripheral-bond-handling with bls_service (PCA10028) and i have problem with unnecessary connection. I want that my...
I'm referring this blog on getting started with nRF51822 and in this same blog, there is a link to a video by Nordic on Introduction to Bluetooth Smart and after watching...
I have two STM8s105 MCUs and two NRF24L01+ modules. Set one as transmitter:
CONFIG: 0x3A
EN_AA: 0x00
EN_RXADDR: 0x03
SETUP_AW: 0x03
SETUP_RETR: 0x00
RF_CH: 0x00...
Hi
I used the boot loader example successfully on the nrf51DK board.
Now I want to use it on my custom board. So I recompiled the boot loader code, with 1 difference:...
I don’t fully understand the nRF51 event NRF_RADIO->END. NRF_RADIO->END identifies the completion of a packet transmission or reception. My question is what triggers NRF_RADIO...
We have a project that involves both battery-powered 'slave' devices and a mains-powered 'master' device (which needs to support multiple slaves and support WiFi). We are...
Hi,
imagine that I have a proprietary characteristic that allows only READ operation (from a smartphone for example) that expose an internal value in my application.
I...
