I want to send a set of 64 bytes data with ble. as I understand, the max data length I can send within a characteristic is 29 byes. when I send 4 bytes data it works fine...
Is it possible to bit bang a 9600 baud UART on the nRF51822 while the BLE softdevice is running?
The reciprocal of 9600 baud is around 100 µs, so the interrupt handler...
Hi Team,
My application is based on nrf51822 SoC in which I am using
BLE and UART interfaces.
There is single UART available and I have used it in communicating with...
Hello,
I am using am using sd_ble_evt_get and sd_app_evt_wait in an endless loop for handling all incoming events.
If I block this loop from executing, I'd expect that...
Hi all
I'm struggling with the easyDMA UART of nrf52. I've got a preview nrf52-DK here where I wanted to make a simple example with the following code but I never reach...
I'm doing a custom board with a nRF51822 FAAG0. I have in it the ST BAL-NRF01D3, with a 0.8pF capacitor.
In the forum I read in a post that some versions of the nRF51822...
Hi everyone,
I am using the nRF51 SDK 10.0.
The documentation for the Debug Logger API suggests sample code like:
uint32_t retval; // Initialize module
retval = app_trace_init...
I want to use the J-link to program the nRF51822 via SWDIO and SWDCLK, every time I click the
