My custom nRF52840 board uses the STmicro STM6601 push-button controller. To keep the nRF powered, the PSHOLD line must be kept high. I have a GPIO set as an output for that...
Hi there,
I am trying the test the robustness of a BLE use-case. This means that i have to create error scenarios and further observe and analyze how it's possible to recover...
Dear all i have a very funny situaton.
I can only send 1 byte in my service data when I increase it to two bytes it doesn't send. and says invalid parameters
When...

Please kindly help to push this emergent issue!!!
We detected CLK signal using oscilloscope as picture below:
We can see that clock frequency is set to...
I have been making good use of the Power Profiler Kit with some impressive results on my nRF52 project.
I would now like to extend the testing to view an application where...
Hi

Hello,
I have developed a custom PCB using nRF52832. It's meant to work as an ibeacon currently and consequently works in a non-connectable, advertising only mode. I will...
Hi,
I am trying to use GPIOTE_PIN_HANDLER in the master nrf52. What is the correct way to read data from slave?
