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,

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,
Is possible to program the nRF52832 with a target voltage between 1.7V to 3.3V? I'm thinking to power supply the MCU with a pair of AA batteries in series.
Thanks...
I am using the "Nordic Uart Service", example to create a simple serial console which allows a user to change settings such as tx power, advertising intervals so that different...
As in the circuit diagram attached where the pin resource is insufficient For one Pin (AMULTI), I design gpio for Button and analog input as 2channel. (This switch uses the...
Hi DevZone,
I am going to apply a Arduino CAN bus shield onto nrf528400 preview DK. I was integrated this shield with Arduino board and a 3rd party BLE module. Now, I am...
I'm basing my PCB design on Nordic's reference layout. The product I'm developing will only be used for research, and is basically a one-off design. How closely do I have...
Hello,
I am using the NRF52832 for advertising every 10s.
However while entering the sleep phase, I noticed some glitches while measuring the current. You can find attached...
I am in need of some guidance around how to simulate multiple devices, with different addresses, on the same NRF52
I am currently developing a test application using the...
