Hi,
I use the secure BLE Bootloader to update the nRF52840 (with S140).
Now I want to add a UARTE to update the STM32 connected to nRF52.
Do you have a solution to do...
Hello,
I am using two nrf52840 DKs to test ble transmission and i2s output. The nRF Connect SDK I use is v2.6.0.
Both of them are ble connected. One sends data to the...
Hello,
I think llpm's sample project is wrong. Evaluation board is not supposed to be communicating.
To verify the defect, the value of the time variable is fixed. This...
