In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
I was wondering what would be a good block size, and saw this in the documentation:
For example, if a module has a table with 10 entries, and each entry is 64 bytes...
Hi Nordic,
I am now trying to use ANT acknowledged data type in reverse direction (from slave to master), and I have some questions:

i am confused in nrf_gpio_pin_sense_t i.e. NOSENSE, HIGH_SENSE, LOW_SENSE.
where is use of this feature ?
why it is required instead gpio_input...
In my application many nodes (acting as centrals) will start simultaneously, as they have common power supply. I am using s132 SoftDevice (4.0). Is the frequency hoping sequence...
Hi experts,
Can we add capacitor to the swdio pin to improve ESD capacity?
We have make some sample that add 1uF capacitor to the swdio, indeed have improved the ESD capacity...

We are planning to use two modules at the same time one for esb and one for standard btle, because the esb is time critical and timeslot api seems to be to low priority. Do...
Hi,
I am using NRF52 DK board. I use nrfjprog under windows to flash controller. But i want to flash under ubuntu. I searched but i found one .rar file.i extracted but there...
This is probably a sign that I should upgrade to nRF52 (with a built-in FPU) but, in the meantime, does anybody have an example of the libfixmath library integrated with an...
Hi everyone,
i have J TAG V8 and when i am using this with keil software and try to debugging then its showing-

I found in documentation that the time to write to flash is between 67.5 and 338 µs.
What conditions influence this time?
-How to avoid long writing times?
I have four wearable devices.
Each of them have 50HZ sample rate, and data length is 20Byte.
I don't want to lost any data, so I want to use indication instead of notification...
