Oswald 0 Posted August 4, 2023 If I connect the sixfab gsm shield on tinker board s usb port it works properly but when I install the shield both on GPIO pins and usb port, I can not see the shield via lsusb. Red power led is on but blue led is not blinking. can anybody help me? Share this post Link to post Share on other sites
tooz 47 Posted August 7, 2023 hello @Oswald, i don't think this gsm shield is on the qualivied vendor list but i'll see if it's compatible with tinker board s r2.0 from the specification. do you have a model name of the shield or a product page link? and if possible, is it okay to share the dmesg logs?
