chip version is 0x00 and all the registers are 0x00 with Raspberry 3B+

[workholic365]

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]

Which sx1302 board are you using exactly ?

[workholic365]

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

[mcoracin]

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

Hi @mcoracin
I have tried ,the result as follow :

t_loragw_com -d /dev/spidev0.0
CoreCell reset through GPIO23...
SX1261 reset through GPIO22...

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

[workholic365]

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

[mcoracin]

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]

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.
