Would appreciate pointer and insignt on learning how to do battery minimum energy LoRa on (a) half a dozen of sleep modes (b) example sequencer C coding with power saving (c) reading list on application/tech notes, etc. TIA
Hello community,I'm trying to create a Lora node with a STM32L4 board and a SX1272 transceiver. I am quite new to Lora and I don't see how to connect them (I have a XBee adp V1.0 for interface).Does someone have any clue about how can I make it work ...
hi, i am using Lorawan endnode example code on stm32wl55jc1, i am successfully transmitting and receiving payload but the problem is i cant do anything else along with the lora , can anyone guide how can i add a task e.g blinking led with 1 sec time ...
On the STM32WL55, when using LoRa and non-continuous receive mode, the RX timeout triggers immediately, i.e. the value passed to Radio.Rx is ignored. This can be demonstrated using the SubGHz_Phy example on the NUCLEO-WL55JC and setting#define USE_MO...
I would like to write C code for the above board. From reading, I believe the steps are as follow. Appreciate if you may help to see if any issue. TIA1. I have Nucleo F103RB (and also F401RE) to be used as ST LINK programmer2. I did firmware upgr...
Is the STM32WL5JC has TCXO oscillator for the LoRa transceiver? What is ppm frequency accuracy?I would like to send 20 bytes to maximum distance using maximum spread factor, SF12. On air time is about 1.2 seconds. From reading, standard bandwidth...
Hi, We have been using the STM32WLE5CB for a while now, using the older die revision Z. Since we have a new batch with the new revision Y die of the STM32WLE5x we couldn't get our firmware working anymore. To try make it work we have tried to use the...
Hello,I'm working on an application that uses the NUCLEO-WL55JC development board. I was looking in the SubGHz_Phy_PingPong example code, and I noticed a macro called SX_FREQ_TO_CHANNEL. To use this macro, it seems you input the carrier wave frequenc...
Hello,This is a continuation of questions raised in this thread.In the STM32WL5x microcontrollers, there is a Sub-GHz radio command called "Set_RfFrequency()". The arguments for this function are an Opcode, and RfFreq. However, you don't actually pas...
I am making a device that is to take pulse outputs which have been converted to wireless LoRaWAN signals, and convert it back again into a hardwire pulse output. For the receiving device, I intend to use a modem board PN 109990166 connected to an STM...
