How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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...
Greetings,
I find it much an arduous task trying to sift through all the SDKs and Documentations in order to find the one specific material that I need. I've installed...
when I use softDevice S110, there exists ble_evt_dispatch function, Can I define event ? if I can, how to define event and how to use event handler . Thank you !
Hi
I want to update the connection parameter and send this request from nrf51822 to a smartphone app. I see there is a function ble_conn_params_change_conn_params() for...
I'm sure there is something obvious that I am missing, but bear with me. The following link references a function called: nrf_drv_gpiote_out_config :

I'm trying the example in the SDK v0.9.1: examples\spi_master
When I load the project, build it, and debug it, all that happens is that it goes into a failed state where...
I occasionally get an NRF_ERROR_NO_MEM error when trying to add a custom characteristic. I'm only using 3860 bytes of ZI data, stack = 2048, heap = 2048 so it seems like I...
Hi
I am working on the ble_central_and_peripheral example in nRF51_SDK_8.1.0_b6ed55f .In this example it is possible for us to connect to 3 peripherals only.But we would...
Hi, are there any examples in C for how to directly access the registers on the chip? I realize this is a super basic question, but all the register access in the examples...
Hi,guys
I set BLE parameters like this:
#define MIN_CONN_INTERVAL MSEC_TO_UNITS(500, UNIT_1_25_MS)
#define MAX_CONN_INTERVAL MSEC_TO_UNITS(1000, UNIT_1_25_MS)
#define...
Hi,
I'm using sd_ble_gap_connect to connect to a set of known address and whitelisted devices. My central periodically (once an hour) needs to check on a known set of devices...
Hello,
I'm looking for electrical parameters in nRF52832_OPS_v0.6.pdf but I didn't find typical impedance values for analog inputs .
Also not found any value for RESP and...
