Problem when joining the gateway

Hi,

I am using a Microchip Lora Mote trying to talk to a gateway. I registered an ABP device in the Sandbox app and configured the device as per instructions in the tutorial page. When sending some strings to Sandbox I got “mac_tx_ok” which stands for “transmit ok, but no response from the gateway” according to Microchip’s user guide, and no message in Sandbox webpage.

The gateway I am trying to connect to is installed in the office next to mine (Mile End Campus QMUL), and was indicated as working in dashboard.

The firmware version is the same as shown in the tutorial.

Can anybody shed some light on this?

Best,
Haoran

Hi Haoran, did you get this going in the end ?
