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 all
I am trying to pair nrf52840 (as a central) with ESP32 (as peripheral).
Now I want to get the service uuid so that i can pass to advertising service in ESP32 code...
When restrating the controller, are there any information stored in memory regarding the paired devices or is this up to each implementation to do this manually.
1. If there...

Hi,
I am working on low power mode with DK to apply optimization to our project.
And I verified DK with ble_uart_app can go down to less than 5uA in system on mode which...
I'm still trying more TCP stress testing similar to this inquiry . However, now I'm getting highly repeatable lockups on the node I am doing testing with.
Application code...
I was doing some stress testing of TCP connections and saw an oddity go by that has me scratching my head.
Here's the order of events as best as I can figure from correlating...
Hi,
I already achieved the update of all available nodes in a mesh network, where the update is injected over a serial connection to one node.
Now my question is, if I...
Hi
I'm confused by the concept of switching slots and sampling slots, or at least the way they are presented as being interleaved. For BLE, I believe that they are required...
