I want to glue a neodym magnet to the back (black plasic case) of the PuckJS.

To chose the right glue I need to know which type of plastic is used by the PuckJS. Or maybe someone already did something similar and has a recommendation which glue to use.

I have something of this and don't know if it's suitable:

My current project involves putting the Puck.JS outside. Is the case waterproof and is it still safe if it rains outside?

If not, which type of case should I use? Maybe there is even a recommendation for a specific type of case for 3d printing? The case should not affect BLE range too much.

Hi Gordon!

Thank you. I experimented a bit and it seems like in the end the accuracy is good enough.

While it seems like the ESP32 would be the winner here, there is one fact that is more important than range. While the ESP32 runs around 2 days on battery I expect the Puck.js to run significantly longer.

I dont't have any expierience with actual battery consumption on the Puck.js but I hope I will get at least some weeks out of it.

Hi,

I am currently working on a project which uses BLE advertising. My code runs on a Puck.js and on an ESP32 board. The signal range of the ESP32 is impressive and the BLE advertisment is picked up from several meters and even behind walls.

However the Puck.js performs badly. I tried to set the TxPower via setTxPower(4) but this doesn't have the desired effect. The documention at https://www.espruino.com/Reference#l_NRF_setTxPower is bit unclear. What unit is TxPower in? Does a negative value means more transmit power or less?

What can I do to improve the range of the Puck.js?

Thank you!
