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...
HI
I use NRF9160 serial_lte_modem to test NBIOT/MQTT, current SDK is V1.6.0 ,and config mqtt keepalive =1200S.
after 9160 connect net, control mqtt connect my mqtt server...

Hello!
When collecting dc1.4v with SAADC, there is an error of 100uv. SAADC is configured in differential mode, with N-terminal connected to GND and p-terminal connected...
Hi,
I've read in these forums and seen the machine instructions within the C code that nrf_delay_us (which BTW is used to do nrf_delay_ms) is implemented by executing a...
Hi team,
I would like to know the default channel used for data transmission and the frequency of the channel.
Also whether the frequency is configured in the softdevice...
What is the purpose of the external capacitors on DECA and DECN? DECA calls for 1uF and DECN calls for 0.1uF. The datasheet calls these out as "Regulator Supply Decoupling...
Hello,
sorry to border you again, but I have a problem that block me for many days. I read all nordic questions on TWI (I2C) but did not found a solution... :(
I have...
Hi,
We are designing a custom Board using nRF52840 SOC.
We are operating it in Normal mode, using an internal DCDC converter
We have used configuration 5 from the...
Hi there,
I need to transmit 33995520 bytes from nrf52 peripheral device to a Windows/Android device. Currently it takes about 13 to 14 minutes to complete the data transfer...
the flash of the nrf52832-QFAB is 256KB. the softdevice S132 is used which consumes 152KB and the compiled file of the BLE_UART only consumes 98KB (after making the changes...
Hi,
We have a product already on the market for about 2 years, based on nrf52840 and nrf52832.
The product receives data from an 'external device' via UARTE, forwards...
I received the product update notification via email. I did not see any additional details such as a PCN which documents the exact changes.
So the questions I have are:...
Hi Devzone,
I have noticed that some examples, like "ble_app_hts" that has strange flash placement like this figure:
There are 3 partitions, each is 8 bytes in top of...
