Hi , Recently I got a sx1302 module with raspberry transfer board , I try to execute with compiling the open source sx1302_hal codes .I tried to test with test_loragw_reg , the result as follow :

CoreCell reset through GPIO23... SX1261 reset through GPIO23... CoreCell power enable through GPIO18... CoreCell ADC reset through GPIO13... Opening SPI communication interface open spidev0.0 OK [com_stat = 0] #this is my test to check whether spidev0.0 could work Note: chip version is 0x00 (v0.0)

I checked the reset pin ,it worked . the spi device could also effect . so does anyone met the same issue ? and may give me some suggestions about it .appreciate your help .

Hi, Have you executed the reset_lgw.sh script which is provided with the code ? Best regards, Michael

Hi @mcoracin , Thanks for your reply . yes ,I executed the reset_lgw.sh script which copied from the tool path according to the instruction .
Do you have some suggestions for my current issue ? Thanks !

mcoracin commented 10 months ago

Which sx1302 board are you using exactly ?

workholic365 commented 10 months ago

it can be found in sx1302 module : should be made by greenpalm

mcoracin commented 10 months ago

I don't know this module, I guess it is an issue with the GPIO configuration in the reset_lgw.sh script. You can use the test_loragw_com to check the communication with the sx1302.

./test_loragw_com -d /dev/spidev0.0

it seemed fail to read . could you find something wrong from above result ? appreciate your help !Thanks !

workholic365 commented 10 months ago

I checked the reset by echo to make it set or reset ,it worked .

mcoracin commented 10 months ago

I can't say much from the logs, either your SPI connection is wrong, or the GPIO pin values are not set properly in reset_lgw.sh script for RESET and POWER_EN pins.

You are sure that this sx1302 board is an SPI version, and not a USB version, right ?

workholic365 commented 10 months ago

Hi @mcoracin, sorry to reply you late , I am doing some tests all these days . I think the issue may be caused by the spi pin , the real spi pin not match . another sx1302 board could work ,have test with the lorawan node and open lorawan server , it seemed normal currently . Many thanks .

I'm having a similar issue. I used a WM1302-SPI-US915-M with no issues, but I had to downgrade to the slightly older WM1302-SPI-US915 (notice no -M), which does not work with the packet forwarder. Are the GPIO pins different between the two models?

Edit: I forgot to do the Seeed Studio setup instructions here. Needed to change some GPIO pin numbers and enable SPI/I2C interfaces, and I'm good to go.
