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,

Hi,
I've been trying to run the zephyr's littlefs sample on Thingy:91 under the ncs 1.2.0 tag, but it seems that the flash_open_area function is having some trouble, and...
Hi,
I have a SPI slave device which outputs 8-bit registers that I have to assemble. For example, I receive two 8-bit registers, a high and a low register, which I have...
When I am going to program a custom board for the first time, can I use example codes from the SDK or should I change anything important on the configuration?
On my custom...
I'm trying to create a simple service that would just provide some data which could get updated internally (for example, via SPI bus). Data may be of a different size, so...
I have a PCA10059 dongle. I have inadvertently configured pin P0.25 as the sleep debug pin and I use active state 0 as I am using off board LEDs with reverse logic. This means...
Hi,
I'm just getting started and tried to run the lwm2m_client sample from the v1.2.0 release of the nRF Connect SDK which I assume is the latest stable version? However...
hai ,
