Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi,
On iOS, is there any way to download files right into the nRF Toolbox "User files" ?
This would be useful for DFU tests, to retrieve my binaries from the web.
For...
Hi everyone,
When I set the radio's transmit power, I can use "sd_ble_gap_tx_power_set" function. If I want to get the radio's transmit power, is there any function I can...
I am using NRF_GPIOTE->EVENTS_IN[0] and NRF_GPIOTE->EVENTS_IN[1] in my software. I had my own GPIOTE_IRQHandler working.
Today I am adding UART module into my source code...

Hello all,
Am I right in thinking that to use the ANT SoftDevice, I basically must use an external 32 KHz crystal, in order to meet the accuracy requirements?
Looking...
What are the main considerations for choosing between nRF905 and nRF24L01+ for an application? Is it just the transmission range (distance) and the frequency? Are there any...
I am trying to write a radio code without using BLE stack here i was able to write down code for initialization of radio and was advertising some random packets. But how should...
