I am using esb in SDK 11 and my understanding is that the radio causes interrupts that are forcing and cannot be disabled. These in turn causes software interrupt 10 to be...
I'd like to read and write data to the reserved app data space while in the bootloader. Is this possible with pstorage?
Because the BOOTLOADER_SETTINGS_ADDRESSS = 0x0003FC00...
Hi,
I am using 'pstorage_update' to store data in the internal flash. Whenever the number of bytes that should be written matches the size of a storage block everything...
Has anyone tried to generalize this example to different sized variables? What I would like to do is allocate a data structure, write that to flash, and recall it at a later...
I've a PCA10036 V1, I change the IC to nRF52822 QFAA-B016. With nRF5_SDK_11.0.0-2.alpha_bc3f6a0 and SD: s132_nrf52_2.0.0-7.alpha_softdevice, the programme started but if I...
Hi
We are developing software for the nRF51 with Keil under VirtualBox. Previously we used the PCA10000 dongle with the Master Emulator and MCP without issue. Now, with...
We are using nRF51822 for our products.
We want to know the min value of "Receiver sensitivity" when we use this chip for BLE.
The Datasheet says "Receiver sensitivity...
hello,
I have a custom board which works fine with SoftDevice+Application , but if i Combine a boot loader hex that i complied it doesn't work. But the same ( bootloader...
I found and implemented an example that gives me a decent idea of how to go about polling for data with the UART/FIFO. However this doesn't give any indication of how to use...
Hi.
Trying to set up the Ubuntu development environment for you nRF52 development kit.
I followed this tutorial:

Can anyone help me reading IO capability in Android? Basically there is a known bug in some Android versions across different manufactures where Android reports wrongly IO...
I want to use chacha20 cypher to encrypt and decrypt a 64 byte message and send it over BLE. I tried using wolfSSL, cifra both of which provides the implementations but there...
Hi,
To measure the transmitted RF power (to reach EN 300 328) we Need some ATT commands to set fix channel and maximal output power. In additional we test the EN 55022...
In this previous discussion on minimizing power consumption on the NRF51-Dongle, it says:
You are using evaluation kit or
development kit and LEDs are connected

My system is a BLE peripheral with 2 states. There is a characteristic that represents the state, and it can take 2 values: 0 and 1.
You can read the state, write it (force...
When the supply voltage drops below 0.6V and then get back to 3.3V the nrf51822 starts up in an undefined state and often some flash pages are corrupt after that. Is this...
Hello,
We're currently running softdevice s310 v2.0.1 with SDK 7.1.0 on the nRF51422-QFAAE0 (ie. rev 2). We're planning on upgrading to the nRF51422-QFAAF0 (ie. rev 3)...
