I think if ( (p_timer->ticks_at_start - m_ticks_latest...
I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Dear Support Team,
We are migrating our designs to nRF52820. With previous IC we saw that Johanson has IPD for atenna filter + matching circuit (e.g.2450FM07A0029), but...
Now we have a new project,in order to long distance communication,we add a PA RFX2411N in our design,now how may I tuning the pi (or T) match network between nRF52 chip and...
Hi All, What is the best way to modify ble_app_multilink_central and ble_app_blinky example codes, so BLE tag can send to ble_app_multilink_central Its own address. The ble_multilink...
My application uses a NRF52 (SD132, SDK 15.0.0), very simple circuit and needs to be extremely low current consumption. I measured the current in conditions of BLE on and...
Hi, I'm having some issues with migrating from SDK12.1 to SDK16 while discovering services.
It seems to connect to Android without much issue, but on iOS the connection...
A project is currently utilizing an NXP module to access the SD card via 4-bit SDIO. I am exploring the feasibility of integrating an nRF52840-based module, and have a few...

Hello,
I'm in the process of developing the HW board for a nRF5340-based product. I need the customer could update the firmware using a serial port (USB or Bluetooth is...
I am testing a number of boards with a QSPI memory module with NRF52840 chip.
The QSPI driver functions all return without error even if the chip is not present. What is...
I have made PCB 32mhz crystal footprint with error. I have used other khz frequency too. Now I can't solder 32mhz crystal is it possible to code nrf52832 and control various...
Hello,
I wanted to test the long range, so changed the primary and secondary PHY to BLE_GAP_PHY_CODED from BLE_GAP_PHY_1MBPS in the advertising_init() of the peripheral...
I'm trying to debug a Zephyr application on nrf52DK. However, due to the use of multi-threading (in Zephyr) I can't use J-Link Debug Server (as I'm used to). For executing...
