we have a 'long lived' tcp connection w/ regular data sends (1hz of 256 bytes for mqtt publishes) where sendmsg() sometimes returns EAGAIN. when trying again it usually works...
our current network provider says that they have a restriction on their sim profile so that the mtu should be less than 1430. however things like pdn_dynamic_params_get()...

Hi,
We are unable to get the correct location (even approximate) using the nrfCloud API for Location based on Single-Cell. For the given "mcc", "mnc", "tac" and "eci" combination...
I am using the nRF9151-DK as an SPI slave . The SPI communication is not working as expected, and the nRF9151-DK is not receiving any data from the SPI master .
I have configured...
Hi,
Does the nRF54L15 support Direction Finding (AoA/AoD) and Channel Sounding together — i.e., can both features run on this specific chip, either simultaneously or at...
Hi,
We use the nRF9151 modem and need the following data from it: Mobile Country Code (MCC), Mobile Network Code (MNC), Tracking Area Code (TAC), cell_id and rsrp.
We...
Hi
We are seeing a strange behaviour when using sd_ble_gap_adv_set_configure() . When we set the advertising data in the ble_gap_adv_data_t to have the advertising flag...
Hi,
We use the FDS to write/update/delete the data that store to the flash.
When operating delete/update the data to the flash for a while, the error FDS_ERR_NO_SPACE_INQUEUE...
My requirement is simple: Want to increase the iBeacon transmit power to (i.e. -4, 0 or 4dbm). In the beacon example, I tried adding in the main loop after calling advertising_init...
Hey Devs,
Would I be able to get a CAD file for the Nordic Thingy's main board. I just found a snapshot of it on the last page of the document labeled PCA20020_Schematic_And_PCB...
Hi,
I just create simple example based on nRF51 ADC examples, using SDK12.3.0 with softdevice S130 v2.
I used PPI + Timer to get sample from ADC. I used TIMER2 to trigger...
Hi everyone and thanks in advance.
I'm new to the NRF52 SDK enviroment and I've been having some trouble with the I2C/TWI configuration. The SDK we are using in the v12...
Hi,
Is it possible to send notification periodically even if there is no change in the value? I create sample code that send constant value periodically over BLE, but in...
I'd like to use new nrfx drivers included in SDK 15. The problem is that I want to use C++ but nrfx header files are for C. The struct initializers can't be compiled as C...
I have a lot of pin_read function. How can i set all port one line? for example P1OUT = (P1.01 | P1.02 | P1.03) or P1IN = ( P1.01 | P1.02 | P1.03 ) I dont know how to use...
I created a simple message mode based on the simple_on_off modle,when I debuged the codes in simple message client,I got an error(app_error),I never changed the codes for...
hello,
I used NRF52832 as a ble gatway.Now i have a trouble that the received signal strength is jumping about 2dBm when the chip loaded program.I test it with Spectrum Analyzer...
Hello! I am trying to prototype a DFU solution that works well for our application. We want to build a network with both normal Mesh devices and with friend nodes (once that...
Hi,
for my PCB, i'm using an NRF52832 as SPI slave, i send an array of 4 bytes {0xA5,0x00,0x01,ff}, but my SPI master receives always a byte (0xff) before 0xA5.
this...
Hello everyone
I have kind of a basic question.
I'm not sure how to manually disconnect from a ble connection. I'm using the ble_app_uart and ble_app_uart_c examples from...
