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...
Hi.
I'm using PCA10028, SDK10.0.0, S130.
If i scan again when it is scanning, system goes halt and reset.
So i want to check it's scanning or not before I make it scan...
We have an RFID application, the tag sends the 10 byte data and the data is read at the Receiver continuously thorough SPI channel to MCU.
Payload of 10 bytes, Enable CRC...
I've been playing around with the multi-central central/peripheral examples and I thought I would modify the peripheral to instead use a service I had written for another...
Hello, I want to detect the any activity of the ADXL 362 and blink the LED ON and it should also detect the inactivity to turn OFF the LED.I am able to generate the activity...
Hi,
We are using the Nordic Semi nRF51822-QFAA-T to do BLE project, but when we test CE/FCC RF test(Conducted / Radiated), there has a lot of noise around 2.4G.
BTW...
Hello,
I try to find the information if there is a softdevice (for nrf51 or nrf52) that supports "LE Secure Connection".
In general, where can I find which bluetooth version...
I'm lost.
Can someone point me to place or the best example of how to send data (any) from NRF51882 to iOS app when app is in background.
Is it possible at all ?
I'm trying out the ble_app_gls demo with the Nordic Master Control Panel app (on Android). What I see is that the MCP can connect to the device without bringing up a pairing...
Hello,
We are working on a third party module from china. We are trying to program it with keil but we are having problem with configuration.
We are using S130 v1 and...
I'm trying to make a BLE device that actually pairs securely. I posted this question on StackOverflow but didn't get any answers - maybe someone here knows more. As far as...
Hi
we have a custom board, where the clock does not start (verified by osciloscope). We do not use an external clock, so from our understanding the command to init the...
How can I use power fail IRQ for wakeup ?
How can I set polarity for wake up pin ?
Which method is better for wakeup, pin, comparator or RTC2 ? application is just two digital...
I'm handling the entire prepared write sequence myself, returning NULL for the memory request and dealing with the Prepare Write and Exec Write etc.
I found that if I send...
New to this development environment.
Blinky compiled, flashed, worked and debugged easily.
On BLE examples. The HTS example eventually loaded after setting the target...
I need a clock output (> 12MHz) from nRF52 for interfacing a sensor.
From the below post, looks like Max possible output is 8MHz since peripheral clock is limited to 16MHz...
