After I get a Disconnected() event, I want to start scanning again, therefore try to call StartDeviceDiscovery() again.
IsDeviceDiscoveryOngoing was checked before.
The...
Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Recently, I try to programme nRF51822 DK communicating with nRF2401e1 DK,unfortunately,which does not success. With setting radio configuration: TXPower,frequency channel...
On nrf52840 I get a current of ~10 uA while sleeping. At the moment I don't run any code and don't start up the softdevice. I go directly to sleep with __WFE(). The result...
Hi All!
Faced with big problem with SCANNING procedure (nRF52840)
We have a BLE network : one CENTRAL and up to 6 PERIPHERALs can be connected simultaneously to the CENTRAL...
I want to detect high to low transitions on 28 GPIO independently. I've read in other posts you can configure 4 pin interrupts or a port interrupt for all pins, but I'm not...
Hello,
I am currently experiencing some problems, when i try using RTT output and the internal clock.
When using an external crystal, everything is working.
The following...
I am working on Ble tutorial of serivces, In step1 they mentioned to declare m_our_service of type ble_os_t. how can I declare that ?I am not sure to consider m_our_service...
Hello
I have been trying to use this repository: https://github.com/NordicPlayground/nrf51-ADC-examples and upon building, i get several errors due to certain header files...
Hi,
I have a Serialization connection working between a Nordic nRF52 CPU (slave) and an NXP CPU (master), using SPI.
The NXP is starting/stopping a BLE Scan on the Nordic...
Hi, I have some questions about the memory map, ram usuage and linker config for the secure bootloader when used with the S332 (4.05 sd_req 0x94) softdevice. I have tried...
USB Virtual COM
Until now, the development has been done by sending the commands via a USB virtual COM. The received buffer of int is processed and sent to the function...
I have an nrf52832 connected to a UART-USB driver with RTS/CTS. CLI manages the UART connection. Using SDK 14.0.
When HWFC is enabled, if a serial connection is NOT established...
Hi, p0.06 is always high lever when the following codes are executed:
nrf_gpio_cfg_output(6); nrf_gpio_pin_clear(6);
Why?
Softdevice is used in the project.
I have searched through the examples and the documentation (BTW the online document links are broken - the offline documentation is nice however).
From what I can tell...
Hello Everyone.
I am doing a project where I need to do a Bluetooth communication of data. I have two nRF51 DK so the idea is to connect a particular pressure sensor to...
I am trying to create a state machine that will be able to turn the Bluetooth radio on/off and possibly change the mode of the BLE service for power testing. I hope to run...
I have created an instance of time using the standard time function in C. I have also linked it to a counter on a timer so I can track how long the device has been active...
