I have two nrf51822AC mcu chips that are integrated on custom boards, and I need to communicate between those two chips (one set as a transmitter and the other as the receiver...
Hi,
I own company that builds a PIC 8-bit devices, and can code at a low bit level in the PIC environment.
I picked up the NRF52 Dev board, and am trying to learn the...
My peripheral device connects with central one very rarely. I decided that I don't want peripheral to negotiate connection parameters with central, just use settings imposed...
I'm developing custom board of nrF51822 CEAA (256k, 16k)
I set my bootloader ROM, RAM just like below
as I understand,
Firmware size should not larger than...
hi,
i just ask about nrf52832.
im using it with keil compiler and trying to divide the memory section (it that will be update and not)
but i have hard time to do with keil...
I'd like to log some debug stuff to a mobile app over BLE, when in a connection, using the NRF_LOG library and the Nordic UART service. I have this working just fine without...
I'm trying to write to specific address on flash memory (data region) for debug purpose using
nrfjprog.exe --memwr 0x3B820 --val 0xAA000000 --verify
but when I read...
So I'm still trying to get my way around the DFU service implementation, and I'm currently having trouble with the first step, which is to enable the control point notification...
Hi.
This is a bit of a combo question:
I recently got the nRF52 10040 and I'm trying out the included examples on uVision5.
I only managed some examples to...
I am working on BLE Applications, I have tested with different devices like Nexus, Moto, Samsung, LG(ble V 4.0). I am getting the GATT Error 133 in Samsung Devices alone(Samsung...
Hello Nordic,
My goal is to control a small device with NRF51422 without any other additional controller. So I’ve developed my own PCB and I’ve used the example ble_app_uart_s130_pca10028...

Hi,
I have an nRF52 chip that has likely exceeded the flash endurance limit.
I am observing that after an ERASEALL, not all bits are erased, but after retrying ERASEALL...
