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 am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hello,
I am trying to upgrade my working projects to SDK15.3 from SDK15.2. All projects work except the bootloader project as there are significant differences in 15.3...
Hi,
If I understand corrctly, the flag CONFIG_NRF_CLOUD_PROVISION_CERTIFICATES=y should only be used once,
after that, the certificates are saved inside the modem.

Hello.
We are developing a device that require a 1Gb qspi memory interafaced with a nrf52840.
So far the qspi driver and the memory inits and the memory respond to some...
It appears that my watchdog timer is running during interrupts that are handled by the SoftDevice and do not cause a return from sd_app_evt_wait. This is described in the...
In migrating a project from SDK 14.2.0 to SDK 15.3.0, I'm also trying to move from the "legacy" non Easy DMA SPI driver to the Easy DMA one. I don't much care whether I use...
Hi,
I've been struggling with a problem with my builds for over a year now.
On some builds NFC works perfectly, but on many it doesn't - and I have no idea why. I can...
Hi, I'm having problems with proper softdevice reinitialization. What I'm trying to do is work out proper reinit solution - what I'm doing is enabling BLE_stack and all the...
I want to store a few parameters in flash. I don't want to use an external EEPROM because it takes an additional space on a board.
Does anyone know how to do it or a sample...
Hi,
nRFConnect is behaving differently for apps on different SDK versions. I am able to do a DFU via script something similar to the one here https://thegecko.github.io...
After much work I can build the nRF9160 at_client sample project and flash it into the development kit. Using nRF Connect, the at_client sample project only prints the line...
Hi There,
I have developed an initial application on SDK11, based on the UART example, with Keil and it worked perfectly with the nice low power that you guys are capable...
Hi,
I have created a project with nRF52840 DK that reads sensors data and transmits them with BLE UART to my smartphone. Everything works fine.
Then, I tried to do the...
i am working on mesh application using two nrf51822 and one nrf2832. I started from light-switch examples. nrf51 set as two server and nrf52 as a client . In server side integrated...
Hi all,
in the datasheet of the nRF9160 is mentioned, that the same antenna can be used for LTE and GPS.
