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 All,
In my application I have two analog inputs coming from two different sources that I have to sample using one SAADC present inside NRF52. As far as I know, NRF52...
Hi,
I'm using nRF5 SDK V12.0, I found a strange problem. That is the UART can send data to PC, but it cann't receive data from PC. However, this problem just arise on some...
Hi,
I need a bit of help to fully understand how ADC works on nRF52832.
I am using a Thermistor sensor like the following to measure temperature:
Epoxy Thermistor...
We would like to use the PPK for automating some of our tests. Is there any documentation on how to drive the PPK over RTT? If push really comes to shove, we can always read...
BLE UART This is a problem that I have discovered while checking
the cause of the connection frequently due to communication error.
It is normal... In the nRF52832,...
Hi,
I added following code in saadc example code to set GPIO pin high/low and monitor it in the terminal. The pull up looks ok, but when I set it to low, the reading never...
We created our own PCB for the NRF52 with a Johanson chip antenna but no matter what we do, we can't get a signal from the Antenna, not even a weak one to show up on the spectrum...
Hello,
I duplicated the project example "nrf51-micro-esb-master" under "proprietary_rf" and got it up and running. I now need to incorporate some timer functionality.

Hi. I'm using nRF51822AC, SDK12.2.0, S130 v2.0.1 as central.
As I've tested by using
err_code = sd_ble_gap_address_get(p_addr);
APP_ERROR_CHECK(err_code);
App returns...
hi
i am using nrf51822. i used the radio tranceiver example and it works well. I am planning to advertise the received packets so that the range can also be increased and...
Hi all --
I have a tricky layout "issue" where unfortunately, I've ended up connecting my I2C device to the BlueTooth module on the side of the module where my VDD isn...
I'm reading the SDK 10's GPIOTE doc and I'm wondering if there is a way to read a GPIO state without generating an event, ie, something like foo = PORTx.pin10 or alike.
...
Hi,
I have a central that is trying to pair with a peripheral. I want this connection to be secure and I want to use ECB for encryption of data. My peripheral does not have...
Hi,
I'm trying to communicate the nrf52832 with a LIS2DH accelerometer and when I'm trying to read 192 (32*6) bytes of data (to empty the entire accelerometer's FIFO) my...
