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...
Hi all.
Knows anyone someone who use this module with power amplifier ??
Rf module nRF24L01+PA+LNA . I test it .. but still have same distance like module with no PA .....
I'm working on designing a very small footprint PCB with the 52832. Not much ground plane (PCB area is 25x30 mm). What would be the general recommendation for a small chip...
Now we use the SDK V11 I2S sample program to collect data of digital microphone. We want to get the frequency of the sound and the dB value size.I don't know how to calculate...
Hi guys,
I want to know if it is possible to get started on developing applications for nRF51822 without using the evaluation kit. I want ot have a couple of breakout boards...
Hi,
I am testing that nRF52832 transfer QVGA still image from image sensor to phone as follows.
nRF52832(nRF52 DK) is connected with image sensor through some...
Hi All,
About DFU.
I want to know about UART DOWNLOAD for nRF51822 with S130.
Can I download the firmware via UART for nRF51822 with S130 ?
It's not OTA DFU.

I'm using Master Control Panel for PC to try to test bonding with MITM security on the peripheral I'm developing, and I suspect there's something wrong with the Master Emulator...
I am using the nRF52 in 2Mbps proprietary mode. I am running my own custom stack to maximize data throughput. There are no re-transmissions in my design. I have a loop of...
In sample code for central devices,, the BLE event handler, on_ble_evt() , handles the `BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST' by accepting the request. Is it possible to...
On pages 49-50 on the nRF51 Product Specification, in section 8.5.2, there's a bunch of current consumptions listed for the Radio with the DC/DC disabled.
Do those values...
