Resolved! How does the STUSB4710 communicate with the ST1S14 to get the requested VBUS voltage?
I am planning to use a STUSB4710 and use the reference schematic from it's datasheet (Figure 7). There is a connection between the STUSB4710 with the ST1S14's feedback pin. Is this how they communicate with each other to get for example 20V or 15V on...
BlueNRG-1: In the BLE_Beacon example, where is the '・' output from UART written in the source code?
I write the BLE_Beacon example to BlueNRG-1 and run it, then '・'(dot?) was output every 1sec.from UART. I couldn't find where this output is written in the source code, so if anyone knows, please let me know.
BlueNRG-LP aci_gatt_clt_read_multiple_char_value() not working properly
Hello everyone I'm trying to use aci_gatt_clt_read_multiple_char_value() function but it are returning error 0x82 (BLE_STATUS_INVALID_PARAMS).aci_gatt_clt_read() function works as expected but I want to read multiple values for optimization purposes....
S2-LP:How to reliably abort RX while in transition through LOCK state
In my channel hopping application the radio is configured to start RX following any frequency change. However the frequency change may be followed by a TX instead so I may need to abort the RX soon after issuing CMD_RX from READY. Table 50 gives th...
Could not add new services to the BlueNRG
@I'm new to BlueNRG. I have choosen BLE_SerialPort_Master_Slave project for my project. I need to connected with my Master(Mobile app) and receive data from the app. I would like to create a new service which is similar to the existng Add_SerialPort_...
Stuck in LORAMAC_TX_RUNNING with I-CUBE-LRWAN End-Node
Hi, I'm using the OTAA sx1276mb1las End Node software provided by I-CUBE LRWAN but I'm having some trouble after sending some Frames to my Gateway, the issue seems to be that MacCtx.MacState gets stuck with LORAMAC_TX_RUNNING, which I need to be in L...
B-L072Z-LRWAN1 - Not able to send more than 11 bytes of application payload.
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...
Configure channel spacing in S2LP
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 ...
Resolved! In bus off condition of CAN protocol, how does ECU monitors the CAN bus?
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.
