Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

As i understood by reading the forum and documents, the maximum advertisement packet length is 31 bytes. That means that devices with custom UUIDs (128bit = 16bytes) may not...
Hi,
I am a hardware designer. I have little knowledge about firmware or software.
Now I want to apply the nRF52832 to an ultra-low power application as a beacon.
I...
I have recently ported my nRF52832 application from SDK 12.3 to SDK 14.2 and have been disappointed to find that the preripheral is locking up after a period in operation...
Hi,
My product have to pass SRRC certification,but the pre-test is fail. The certification lab need to test RF frequency at 2402MHz, 2441MHz and 2480MHz separately,and the...
I have a nRF9160 DK that I am trying to get on a network. The iBasis sim does not appear to be in the coverage area, the SIM activated, but has not had both LEDs 3 & 4 blinking...
Hi,
I have nRF9160-SICA Modules with me and I designed a custom board for them. I do not have the nRF9160 DK.
I want to know if there is any way to program nRF9160 using...
I have two TIMER instances, TIMER1 and TIMER2, both setup to Clear Mask on timeout (aka restart). I use TIMER1 and PPI to trigger ADC measurements every 5msec. In the ADC...
I've been documenting this issue and asking questions here:
Intermittent device reset in modified ble_app_beacon example
Since I need to post a proprietary schematic,...
Hello,
I was examining the power supply part of the Thingy and I noticed that the charging current is set to 0.5 C, wich is 720 mA (checking XR6804's datasheet it seems...
In order to evaluate the nRF9160 for coming projects, I need to know if it is possible to use Keil as the development platform for the device.
We have a very large codebase...
Hi, May be it's some what basic but I'm not able to update my pwm value. I'm using sdk 14.02 with softdevice in SES. This is my code:

fds appears twice in ble_ots:
1. In ble_ots_init:
err_code = fds_init();
2. on_disconnect
err_code = fds_gc();
It does not look like fds is really used in ble_o...
