Hi,
My settings are:
NRF_DRV_SPI_FREQ_1M, NRF_DRV_SPI_MODE_2, NRF_DRV_SPI_BIT_ORDER_MSB_FIRST.
I'm trying to readback 0xD8. The proper value should be 0x71. Instead...
Hi,
I am trying to use the nrf52 in serialized mode, where I was successfully able to program the connectivity board (using SDK 11.0.0) However if I try to load any of the...
We are using a module which has nrf51822 on it. Before we have programmed it, we were able to see it when we scan for ble.
But after we program we could not able to detect...
I am building an automated test stand for programming our production devices. After programming, I need to pin-reset the device to leave debug mode so I can get an accurate...
We have an BLE application that we are targeting the nRF52 device for. The application demands using a UART interface to communicate to a host processor. In addition, we typically...
Hi all,
until now, I used nRF51 Chips on my board. I programed them trough the nRF51DK(PCA10028). But now I would like to work with nRF52832 Chip. I have a nRF52DK(PCA10040...
