I am using I-CUBE-LRWAN SDK LoRaWAN_End_Node application. In LmHandler.c file inside LmHandlerSend() function LoRaMacQueryTxPossible() fails with LORAMAC_STATUS_LENGTH_ERROR. I have tried with higher data rates and also tried disabling the adaptive d...
Hello! I'm trying to develop a simple radio with S2LP, my objective is just to send and receive simple packets.However I've detected that the default channel spacing is set to ~100KHz, at least in my unit.I want to change that to 25KHz, according to ...
In Bus -off condition , the ECU(node) disconnects from the CAN bus.So how it monitors the transfer and receiving of the message signal in CAN bus until Bus -off recovery stage is received.
How do I get the expected payload length from the PHR?The PHR isn't expected to be available after the SYNC_WORD detected interrupt so either the FIFO_RXAF threshold interrupt or RX_DATA_READY interrupt should indicate data in the RX FIFO and the len...
I'm trying to connect STEVAL-SPIN3200 with STM32Cube programmer however when I do it appears either of these message: Warning: Connection to device 0x444 is lost or Error: No STM32 target found!I've tried all different solutions but still can't conne...
Hello,I am designing a USB-C Power Delivery circuit where our product is the source (NOT the sink). The system can be enabled/disabled via a user button, meaning the USB-C PD portion will lose its control supply power. I would like to be able to achi...
Is it possible to enter TX mode so it immediately starts sending the preamble and header bytes before any data is in the TX FIFO?ie. Can the TX FIFO be filled during state transition (READY->LOCK->TX 70us+26us) and preamble time?Or will the TX Underf...
Hi, I am evaluating the current consumption of BlueNRG-LP using STEVAL-IDB10V1 and i am a bit confused with the expected and actual device's currents.According to the datasheet, peak TX current during connection at 0dB is 4.3mA, according to Current ...
