How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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...
each time I start my program (nrf51 device) I get an error code I save in flash to check it at next restart. I can read error code 0x20
is this a correct error code and what...
Hi,
I try to generate a PWM signal on PCA10040 with the nRF52832. To do that I copied the code from the Product Specification into my application, but nothing comes out....
Hi,
I made my prototype board using the nrf51822 chip. for this prototype i use an on-board connector + external programmer to flash the nrf51822 chip.
that's work...
I am looking ahead to the time when I will graduate from using the nRF52 development board to building a custom device with the SoC. The PCA10036 chip will obviously not be...
Hello,
I am almost finishing developement of a BLE module using nrf51822.
For mass production, I hope I can program Softdevice/Bootloader/Firmware to 10 nrf51822 using...
Hi
I want to receive and send a lot of data in a short time (connection Intervall is set to 20ms). And I get the App-Error 0x3004.
I found this definition for the error...
Hello,
I am currently trying to figure out a problem with my mesh. If I stop the event handling of one node, other nodes in the network will fail to send data from this...
PAN #9 in the nRF51822-PAN-v2.4 document provides a workaround for non-functional OUTINIT. This question and this one improve the workaround and state it's unnecessary in...
We have used the first version of the S132 softdevice with the Engineering A version of the nrf52 chip. Now with the newer Engineering B version, we have moved to the second...
Hello Everyone,
i am trying to simulate the circuit using Proteus so can anyone tell me where can i find the Pspice model files for the Nrf51EVB is it available? any suggestions...
Hello to everyone.
I write code for NRF24LE1 using KEIL and rtx tiny. But i have some problems.
When i power on my device, programm don't run correctly, but when hard...
Hi experts,
The softdevice is s120. I get error code BLE_ERROR_NO_TX_BUFFERS after calling sd_ble_gattc_write() several times. I want to ask what does the tx buffer mean...
I have a strange problem on my target nRF51822. When I try and use the UART interface between my nRF51 and my host MCU, it causes the nRF51 to reset and the RTT terminal to...
Hi,
I've been playing with NFC on nRF52. It sends "Security Manager TK Value" over NFC. There is currently no option to use LE SC over NFC in examples, which is to send...
