ERROR 19 when calling ble_nus_data_send

Hi, I am getting an error 19 which causes a reset after some time running a modified version of the ble_nus peripheral example may someone guide me on how to sort the issue please as im relatively new to Bluetooth. in my application, i have a peripheral nrfd2dk (using a modified version of the ble_nus example) and i also have a central nrf52dk (using a modified version of the ble_nus_c example) on the peripheral i have spi running read running in a main loop such that i fill up a buffer of 242 with gyro readings with a terminator and an initiator. this can be seen below in the image. from some research the error is due to the tx buffer being overly filled. i am not using the BLE_GATTS_EVT_HVN_TX_COMPLETE as I'm not sure how to use it hence I have some delays (which i would like to remove

nRF9160-DK LTE Link Monitor, no respons

Hi all, I have tried to follow the step to get up and running with my new nRF9160-DK, however, I am not sure if the Application FW has been successfully updated (how would you know?). I afterward tried to update the application modem (successful). But, once I try to follow the step to Provisioning the nRF Connect for Cloud certificate using LTE Link Monitor, the device is not responding. I tried pushing the RESET button but nothing happens. What could be wrong? Any ideas?

Using the PPK2 with test scripts

Hi, I just got my hands on a PPK2 and I really like it's ease of use with the Power profiler software. But I would like to write my own scripts to automate my tests. I saw a few forum posts talk about an API but it seemed like those were for the older PPK. So does the PPK2 have an API/library? Or can you provide any examples on how one can go about writing test scripts with the PPK2? Thanks, Gowtham

Change Scan Parameters using NCS

What I'm trying to do, is probably very simple. I hope. In the following code which works fine. I want to scan not using Coded PHY Then change back to using Coded PHY I'd be grateful if you would show me the proper way to achieve this please. BT_SCAN_CB_INIT(scan_cb, scan_filter_match, NULL, NULL, NULL); void initialise_Coded_PHY_scan(void) { struct bt_le_scan_param scan_param = { .type = BT_HCI_LE_SCAN_PASSIVE, .options = BT_LE_SCAN_OPT_CODED, // JC .options = BT_LE_SCAN_OPT_CODED, BT_LE_SCAN_OPT_FILTER_DUPLICATE, .interval = BT_GAP_SCAN_FAST_INTERVAL, .window = BT_GAP_SCAN_FAST_WINDOW, }; struct bt_scan_init_param scan_init = { .connect_if_match = 0, .scan_param = &scan_param, .conn_param = NULL }; int err = 0; bt_scan_init(&scan_init); bt_scan_cb_register(&scan_cb); /* Set Scan filter */ err = bt_scan_filter_add(BT_SCAN_FILTER_TYPE_NAME, dev_name); if (err) { printk("Scanning Name filter cannot be set (err %d)\n", err); return; } // err = bt_scan_filter_add(BT_SCAN_FILTER_TYPE_MANUFACTURER_DATA, MANUFACTURER_ID); // if (err) { // printk("Scanning filter Manufacturer ID cannot be set (err %d)\n", err); // return; // } /*

Issue about nRF5340 Network core bootloader

My Current nRF Connect SDK version: 1.5.0 I am trying to follow this reference https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.0/nrf/samples/nrf5340/netboot/README.html to test the network core bootloader. Instead of using samples/bluetooth/peripheral_uart, I use zephyr/samples/hello_world. devzone.nordicsemi.com/.../0181.prj.conf This file is the prj.conf that I use. You can see that I also enable the CONFIG_SECURE_BOOT=y. After I build, I try to flash net_core_app_moved_test_update.hex this hex file. The MCUBoot just ignore it and doesn't start the update in Network core. However, if I do CONFIG_SECURE_BOOT=n. It works fine. I can see "Done updating network core" show on the uart console. Please advise. Thanks, Jason

Hi there, When I program my nrf24le1 in Keil uVision, I notice that when I load the program to the flash memory of the connected motherboard6700 with the nrf24 radio module on it, it generates a nrfgo studio nrf8001 file. Does anyone know why this is happening and how I can change it? Thank you

Keil Cannot Open Header files for hal_adc.c

Hi, I am using Keil 5 (downloaded with this link: https://www.keil.com/demo/eval/c51.htm ) and have downloaded the nrfProbe to this file. This is being used to program the nRF24LE1. I have gone through the first tutorial of this (the short main() example that only includes the header and everything sucessfully compiles. Now, when I add the hal_adc.c file to the HAL folder (see second tutorial) I get tons of errors that Keil cannot find the correct headers: I have added all of the hal folder to the project. Does anyone know how to get around this? I tried manually adding all of the .h files to the HAL folder but that did not work. Thank you
