I was wondering if it is possible to do HTTP requests with the nRF9160 just by using AT commands? Since this is usually possible with such kind of modules.
The reason is...
Hello everyone,
I've got a three type of devices: 1 Central device, 2 Peripherial devices, and mulitple beacons. Central is connected with two peripherial devices with...
Hi Devzone,
We are using the nRF52 DK in a prototype which is under stress, and we noticed that any bending of the board breaks the BLE connection.
To easily replicate...
