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...
I'm working on a central device. I'm using 52832, SDK11, SD2.0.0
I accidentally used a peripheral device that doesn't have the right service UUID that my central device...
I'm using nrf_delay_ms to trigger a series of beeps though a speaker using PWM, but I seem to have intermittent problems with this when the device is connected.
Basically...
I am trying to get fstorage to work, but I seem to miss some of the symbols needed: "error: 'NRF_EVT_FLASH_OPERATION_SUCCESS' undeclared". These are declared in softdevice...
Hi all,
I am using a BLE nano 2, which is based on the nRF52832. I am trying to measure small capacities of a few pF with this method:
wordpress.codewrite.co.uk/.../...
I want to connect a central and peripheral and only have ble on when the peripheral senses a certain event that exceeds a threshold. Do the devices need to connect on startup...
Hi Nordic,
I’m H/W engineer, dedicated in development of radio circuit. I ask the question because we’d like propose your Nordice nRF52840 to our customer when replying...
I am developing an application which uses 2 nrf52 running sdk 12.3 and softdevice 132 V3.
The central device appears to be saving and whitelisting the two peers, but it...
Hello!
We designed and manufactured board with nRF52832_QFAA. The NFC pins was configured as IO and connected to sensors. The problem is that we see that those pins get...
Has any-one been successful waking up a sleeping 328P via a NRF24L01 PRX IRQ interrupt?? My scenario is as below.
Establishing a two way communication between two arduino...
Color sensing not working after DFU. No color reflection LED activity noted. I would like to have more detailed info on how the color sensing code translates the raw color...
Hello.
I need to use LESC numeric comparison pairing.
It seems that the PIN is automatically and ramdomly generated after the connection occurs.
I would need to manage...
I am running a nrf52 with IOT sdk's Cloud CoAP example. I am wondering about the parameters that I would need to integrate this into a product. These include the stack size...
Hello,
I am using 52832 to test ble data throughput. When two devices are close to each other, the throughput can reach 80kB/s, but if the distance is about 4 meters, the...
