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...
Hi.
This is a bit of a combo question:
I recently got the nRF52 10040 and I'm trying out the included examples on uVision5.
I only managed some examples to...
I am working on BLE Applications, I have tested with different devices like Nexus, Moto, Samsung, LG(ble V 4.0). I am getting the GATT Error 133 in Samsung Devices alone(Samsung...
Hello Nordic,
My goal is to control a small device with NRF51422 without any other additional controller. So I’ve developed my own PCB and I’ve used the example ble_app_uart_s130_pca10028...

Hi,
I have an nRF52 chip that has likely exceeded the flash endurance limit.
I am observing that after an ERASEALL, not all bits are erased, but after retrying ERASEALL...
Hi, does somebody know why in Segger embedded studio program goes to ses_nrf51_startup.s line 35 ISR_HANDLER NMI_Handler and sits there. I'm trying ble_app_cscs_pca10028_s130...

I'm trying to program the bootloader together with an application+SD132 3.0 on the nrf52, but my device gets stuck with the bootloader when I finish programming it...
Hello, I used s130, nRF5_SDK_12.1.0_0d23e2a, SoftDevice 8_9_0.
Is there any example to study the central bond?
I use the examples->ble_central->ble_app_uart_c, the following...
Hi All,
I have hardware setup which has four or more beacons in peripheral mode at particular radius ( approx 10 m) and have a beacon in central mode.
The central beacon...
I'm using the Nordic as a BLE solution, and it is just passing along data through the UART to another chip through the UART. However, I'm not sure how to just pass the data...
Greetings,
I am using pynrfjprog (9.0.0) to write a HEX file to an nRF52 device on the nRF52 DK. I am wondering if there is an easy way to verify the write using API.py...
We're looking to implement buttonless DFUs with the NRF52 and are a bit confused how to send 0x01 to the control point of the service. Is this a control point that is already...
