Hi there,
I am getting some error in my SAADC measurements and I believe it's due to the R_INPUT forming a parallel resistance with my voltage divider at the input (the...
Hi,
I am measuring the current during sleep, after the sequence, __WFE();__SEV();__WFE();.
With NRF_LOG_ENABLED set to 1, the current is about 486 uA. With NRF_LOG_ENABLED...
Using: nrf51822, SDK 10.
My application needs to use TWI0 and SPIS1 at the same time. However if I enable TWI0 and then SPIS1, when I run nrf_drv_spis_init() I get NRF_ERROR_INVALID_STATE...
I am working with the SDK 13 ble_app_att_mtu_throughput example. With the SDK 12 example, it seems to require the SoftDevice to be loaded with the arm5_no_packs example. The...
Hello,
I'm designing a project with the nRF52832 where I will use an external SPI ADC.
For debug and backward compatibility purposes, I also plan to use the SAADC.
The...

We are trying to have a thin beacon design. But we are having difficulty in finding low profile inductor for dc-dc converter matching the recommended value of 10uH...
I'd like to use Logic Analyzer in uVision 5.2 and ulink2 for analyzing variables in nrf52832.
In my understanding, I need to use SWO and configure Trace setting properly...
Hi,
I need to capture a demodulated, manchester encoded signal (16 bits long). The data rate is about 50kHz (give or take). Currently, I am configuring a PPI with timer1...
Hello,
I'm using nRF52840 which is surpport Bluetooth 5. I couldn't understand why it can do 8 X range and 2 X data rate than Bluetooth 4.2.
Besides, how to use Bluetooth...
I observe strange behavior while reading value for long characteristics.
I have characteristic 100 bytes long (read only).
In GATT client I must read value with subsequent...
