I'm transmitting 1 byte of data via HAL_UART_Transmit_IT(). After this byte is being fed to the UART HAL via the abovementioned method, the HAL_UART_TxCpltCallback() callback is being fired (which is completely normal). The problem comes during the c...

Base assumptions:1. Testing equipment – X-NUCLEO-L053R8 base board with X-NUCLEO-IKS01A1 and X-NUCLEO-IKS01A2 expansion boards.2. Magnetometer devices under consideration - LIS3MDL on X-NUCLEO-IKS01A1 and LSM303AGR on X-NUCLEO-IKS01A2.3. Mag...

Disabling UART_IT_RXNE before HAL_UART_Transmit_IT() and reenabling it after some explicit delay in HAL_UART_TxCpltCallback() workarounded the problem. I guess HAL ISR support is not coded by the greatest genius in the world.... Indeed, I plan to avo...

It happens no matter if I inspect the HAL flow and the registers or not. If I put just a single breakpoint in the reception callback (HAL_UART_RxCpltCallback()) I see it being called, even so there's totally no data on the RX line (explicitly checked...

The problem was not related to any sensor - it stemmed from incorrect mktime() function, which led to incorrect sample timestamps.
