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'd like to use SPI and I2C simultaneously on nRF52832. But I came across this post which says "if you use SPI0, TWI0 is not available". Does this prevent me from...
I took the I2S example from SDK15 and while compiling I am getting the following errors. I tried but I am not able to solve it. The same happen when I have taken twi example...

I have 2 app_timer instance, one is used for longer sleep like 24 hours, and other is used to blink led when device is performing...
If you are broadcasting in normal mode, this code will not report an error. But if you are broadcasting in long range mode, this code will cause a FATAL ERR. If you are broadcasting...
I am wondering if it's possible to conduct a serial UART loop back test on nRF. For example, if I use a wire to connect the TX and RX pins together, and send something out...
My understanding is that Thingy:91 HW doesn’t support FOTA update of nRF52 from nRF91 since the reset control line isn’t connected from nRF91 towards nRF52. My understanding...
I am working with the udp example in nrfConnect for the nRF9160
I see that CONFIG_UDP_DATA_UPLOAD_SIZE_BYTES has the value of 10 (bytes of payload). However, I do not see...
Hi
I have my custom board with nRF9160 module running Serial Lte Modem application, and an external MCU talks to nRF9160 over UART and access using AT commands. The custom...
We are using nrf9160 and Modem firmware 1.2.3. This might be a regression of this bug .
Our concept is to switch the modem on via lte_lc_connect_async(), exchange some MQTT...
Hi,
I have a requirement, using the latest mesh sdk ' nrf5_SDK_for_Mesh_v5.0.0_src ' on nRF52 Development kit(PCA10040), I want to generate the temperature data from DK...
Hi,
this is my first time trying to use nrf connectivity tools, and my setup is a bit strage (and I have no clean DK setup to compare with:-(
I have to update firmware...
I am developing an IEEE 802.15.4 Application on the nRF52840 using the Radio Driver (v1.8.0) . I have a problem with the transmit call function. Very often in nrf_802154_transmitted_timestamp_raw...
I wrote a program for nRF51822 and compiled it with keil. The app, boot, and sdk are combined and written to the chip. However, if I write using nRF Connect Programmer, it...
