hi support team,
when i testing wifi location, i found out one problem:
nrf_cloud_rest: Failed to encode location request, err: -12
that is this code in nrf_cloud_rest...
We need to set a GPIO pin in MCUBoot to activate an external USB hub chip so the USB DFU will work. I would like to do this with code in our project rather than directly modifying...
According to the nRF52832 Product Specification, “A step increase in supply voltage of 300 mV or more, with rise time of 300 ms or less, within the valid supply range, may...

Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
I was reading this press release:

Yo!
I'm very concerned by what I hear about Bluetooth Low Energy security. According to this guy , who presented a paper on the subject at a USENIX conference last year...
Any experiences about analog sensor LM35DZ? I used this example: main.c
The LM35 data sheet says it will operate from +4V to 30 V supply. I'm use supply only Vcc pretty...
Hi all,
this is not a question per se but rather a warning to those who are attempting to debug Flash related operations with the SEGGER J-Link GDB Server (v4.84a for Linux...
I'm using API 2.1.3 and I'm having problems with SendData blocking forever at the end of a process. I placed access mutexes around each method call to the library, as well...
Dear Nordic Developer Zone,
I have modified the ble_conn_params.c file in order to be able to negotiate new connections speeds between IOS app and Nordic nRF51822 chip...
Hi,
Regarding the bond_info_store() routine, I am having issues where after several calls to this function (client pairing forget/reconnect), my p_bond gets corrupted. This...
Hi, I am developing a BLE application using SPI and TWI. (Using nRF51822)
This discussion is about my survey in development zone for future develop the TWI part.
I want...
I'm calling ble_bondmngr_bonded_centrals_store in response to BLE_GAP_EVT_DISCONNECTED as is the case in plenty of sample code, but when ble_bondmngr_bonded_centrals_store...
Hi Guys,
I have managed to get the BLE DFU demo service working fine (dual bank) on nRF51822 EK. I use a Linux Python program ( bitbucket.org/.../nrf51_dfu_linux) (with...
what is the detection speed, when the beacon
enters into a wall unit area? With their 868 beacon they can
detect in 0,2 seconds. Is the nRF51x22 in sleep mode and does it...
For our application, As I used 24LU1(host) with 51822(device) be the platform.
I hope to transmit Audio data with 8 kHz, 10 bits data format. To commit the requirements ...
Hi,
I have installed "mastercontrolpanel.3.4.0.8098.x86.msi" on my PC, I could not find my master dongle after runing it with my dongle be inserted in USB slot. The screen...
