I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
Hello,
Brand new bluetooth 5 standard allows to create data packets up to 255 octets.
So, does maximum size of advertising data in Nordic devices comaptible to bluetooth...
Hello, when using sd_ble_gatts_hvx(), I keep getting 0x3401 error. I googled it and it appears that it's because I might not have the notification enabled.
But I very much...
OK. Weird question. I know, but that's only because I'm in the middle of a large program that I'm reading, believe me, I had done my fair share of homework and I understand...
I can't seem to get any of the UART examples for the NRF52 to compile on Eclipse. Eclipse is complaining that there are two definitions for uint8_t, one in _stdint.h and another...
Dear developers,
Currently, I am studying the new SDK 12.2. Now, I'm reading flash storage module. It seems very useful.
Just a question: While Persistent Storage module...
So it points to the ACTUAL value of a characteristic. So why do we need that function "ble_hvx_push()" (forgot its name, sorry, but you know what I mean) for? And what's with...
hi dear Engineers!
if I use sd_ble_gattc_primary_services_discover(..) with NULL last parameter , all SERVICES discovered OK:
start_handle=0x0001;
err_code = sd_ble_gattc_primary_services_discover...
We have a device which needs to survive dishwasher conditions. We believe most dishwashers operate up to 71C, but may reach 82C during 'sanitation' phase/drying.
This is...
Hi,
I'm using nRF5_SDK_12.2.0_f012efa and s132_nrf52_3.0.0_softdevice. We want to do the OTA on it. Before I add a DFU service to make it switch to bootloader, I have use...

Hi,
I am trying to initiate Firmware Upgrade using the nRF Connect Mobile Application (also tried using nRF ToolBox).
As described in the below link -

The footprint of sd_ble_gap_connect() is:
uint32_t, sd_ble_gap_connect(ble_gap_addr_t const *p_peer_addr, ble_gap_scan_params_t const *p_scan_params, ble_gap_conn_params_t...
This is what I believe, of course, my beliefs are flawed, so please DO point my errors out:
There is this attribute table on server/peripheral devices. The actual...
Hi，Nordic
I have one nRF24LU1P device, when I make it as USB Dongle, I will use :
