2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Hauv peb lub chaw haujlwm muaj cactus uas tsis tau txais kev saib xyuas nws tsim nyog. Txij li thaum kuv ua haujlwm ntawm lub tuam txhab IT thiab xav sim nrog LoRa, cov kev daws teeb meem uas tsis muaj server thiab AWS, Kuv tau hu peb cov cactus Steeve thiab txuas nws mus rau huab. Tam sim no koj tuaj yeem saib xyuas Steeve los ntawm txhua qhov chaw hauv ntiaj teb siv lub vev xaib Kuv tau ua rau nws: Steeve lub vev xaib interface.

Khoom siv

1 cactus / koj nyiam tsob ntoo
