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...
I want to create voltage divider for ADC input so I need reference voltage for it. I was wondering if I take it out from DEC1 pin? Any how if I measure voltage from DEC1 pin...
I am developing an application on nRF52 wich simultaneously acts as a central and peripheral and I am using the Peer Manager to manage bonding. The central needs to stay connected...
I have the PPK measuring a custom nRF52-based board. The board consists of the nRF52, a I2C sensor, and bunch of caps (210uF worth). We built a custom board to do current...
We highly anticipate it will but wanted to ask here before we might ask Nordic Support to confirm that the nRF52840 will make use of the ARM TrustZone CryptoCell to provide...
I'm looking to design power management circuit for a 3.7V Li rechargeable battery powered wearable sensor design. Any such reference design would be greatly helpful!
Thank...
I'm developing a device that's supposed to establish an encrypted connection with an Android device and I've gotten PM_CONN_SEC_ERROR_PIN_OR_KEY_MISSING during connecting...
I have the Type 4 Tag sample application running and I can read and write the tag without any problems.
I'm getting a little confused reading through the sample application...
Hello,
I am working with the GPIO tasks and events feature on my nRF52832 DK. And I noticed some strange behaviour. I want that two Pins will toggle if some timer events...
Hi,
Please help me with the following theoretical situation:
I have a NRF52832 running HID profile, mostly sleeping.
From time to time, an external interrupt occur (GPIO...
Hi,
I am trying to get the data written from a central (a smartphone in my case) to one of the characteristic of my peripheral using write request. The problem is that...
Dear developers,
We had a working application with SDK11 SD2.0.1 that we have migrated to SDK12 SD3.0.0. With SDK11 we could successfully bond to multiple peripherals and...
Hi. I use the nRF51882 and Arduino ide for developing. My main goal is turn on and off the Led thru the Bluetooth interface. But when I use the UART service for it I have...
I am seemingly haunted by spurious 'soft resets' I cannot seem to find a good explanation.
I have an application that is to be dormant until activated. When waking up I...
