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 use nRF24LE1 configured for power down on register retention mode with RFRx active.
When the CPU is on power down i don't have any interrupt from RFIRQ.
Init configuration...
I downloaded the power consumption example code to a nRF51-DK to measure the current consumption during SYSTEM ON and SYSTEM OFF state.
For the SYSTEM ON state, I used...
On our custom board, we have a dedicated hardware reset IC which toggles the nRF51822's nRST line low in response to a magic button press. The nRST line has an external 100k...
Hi,
it's possible to decide if send a scan req to a peripheral device? I want to send a scan req only to the peripherals that have a specific adv packet...it's possible this...
So, I am working on a handful of nRF24L01 to test some ideas out with radio devices and read thru many example source codes, libraries and datasheets and now I am going a...
Hello everyone
I want to develop a prototype by using nrf51822 but the problem is i did not find information concerning the packages please i request you to provide the...
Hi,
I know it possible for a nrf24l01+ configured as RX to receive communication from several nrf24l01+ configured as TX. (because RX has 6pipes.) I tested and that works...
Hi,
Loaded SDK8 S110 softdevice and application to nRF51822(pca10001), then the application works well. When I want to reload the sofedevice by nRFGo, I get the error message...
Working on a remote monitoring system.
Ethernet solution is on the table now.
But it needs to have extra chipset on board to do so.
I haven't had a chance to look into...
Is there any way i can get UTC time?
Is there any real time clock which keeps track of the time even if the chip is off?
I am using nrf51822 and require the UTC time...
Hey everyone,
I'm having problems with my app's ram usage as you can see from my previous questions.
I've tried this little piece of code:
void memcheck(void){

hello friends,
Im developing an application where im trying to connect a central and a peripheral but since the signal strength depends upon run time environment i am getting...
The App ~ BLE Stack is the device, Central is smartphone.
is correct?
I don't understand this sequence.
Do not adv_data_set and the adv_start before the scan?...
