Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
I noticed that the ram setting in this example is from 0x20003440, this means only less than 1KB is for application. But the example in sdk 12.1 the ram is from 20002078....
We want to use IoT SDK where two or more nRF52 chips would talk to each other via 6lowpan, in that case is the ble enabled router necessary for such communication?
I have an nrf51822AC chip connected to another ARM based processor which provides a CAN interface. The two are connected via the UART and we are using the ble_connectivity...
Hi, in the current project I'm working on, I need to develop an Eddystone beacon with UID and TLM frames configured by default. Based on the experimental_eddystone example...
Hi, Nordic
I need write some information to flash, then power off and power on, nRF52 still can read previous information. But now, nRF52 can not read, maybe ESB is still...
Hi,

I have just read nRF52840 Engineering A Errata v1.0, it looks like nRF52840 is like swiss cheese.
When can we expect some solid version of nRF52840 chip on the market?
Hi DevZone
Does the SWF switch at the PCA10040 automatically switch to the antenna I have put on my connection probe? ( www.digikey.com/.../1775923)
Thanks in advance...
