Porting to STM32CubeIDE #1153

Closed kvkc97 closed 3 years ago

kvkc97 commented 3 years ago

I would like to port LoRaWAN Stack for a custom board built using STM32WB55RGV6 controller and LR1110 driver. I am using STM32CubeIDE for the same. Can I port and use the stack in STM32CubeIDE?

Pirakutu commented 3 years ago

yes you can, i have a version of the stack running on a stm32wb55, with the LR1110, on CubeIDE. It works well.

kvkc97 commented 3 years ago

@Pirakutu I have ported the stack to CubeIDE to work with STM32WB55RG controller. The RF communication was checked with LR1110 IC and the controller and packet was received at the gateway. However, after including the MAC layer in the code, the code gets stuck at SPI transmission command. Could you please share your code so that I can use it as a reference?

Pirakutu commented 3 years ago

What do you mean after including the mac layer?

Does it get stuck at the busy pin or at an SPI command? As these are 2 different things.

kvkc97 commented 3 years ago

I have tested the LR1110 IC with STM32WB55RG controller using STM32CubeIDE and packet was received at the gateway. Afterwords I added Mac layer ( Mac, peripherals, LoRaWAN folder from apps) and made necessary changes in boards folder for STM32WB55RG controller and called the Lmhandler functions in main.cpp as given in this example. On running the code, it gets stuck at SPI transmission (it works well when communicating directly using IC). Busy pin is working fine and is set low as required.

I have updated the code for SPI and the code is not getting stuck. However some other errors are displayed. I was testing for LoRa transmission with LR1110 IC in OTA mode using LoRaMAC code. The Join request is successfully sent to the server and Join accept is generated from the server and is passed to the gateway. The gateway also forwards the packet. However the packet is not received at the end device (custom board developed using STM32 controller). I have attached the Join request and join accept messages. The IC is going to rx mode after transmitting but packet is not received. At time the IC goes to busy after TX mode and gets stuck. At times it goes to RX mode. A few times when in RX mode, interrupt for preamble detection is generated but no further packet is received and most of the times preamble detection also is not done. What would be the issue? Is it due to the PLL error generated. Join request at server image Join accept at server image Join request and Join Request at gateway image

which LR1110 driver files did you use? i had problems using the newest ones. Had to go back to version 1.0.0.

kvkc97 commented 3 years ago

I used the latest version given in the following link https://github.com/Lora-net/lr1110_driver Did you go back to version 1.0.0 of the same driver?

Pirakutu commented 3 years ago

Yeah, i went back to the version 1.0.0 of that same driver (i saw that was the version included in this project and hoped it worked that way).

kvkc97 commented 3 years ago

Hi, I reverted to version 1.0.0 and tried the code. The errors are still present. Also I have opened an issue in LR1110 Driver github page regarding the PLL error. The link is https://github.com/Lora-net/lr1110_driver/issues/16
