Hi,
My questions is related to this one: https://devzone.nordicsemi.com/f/nordic-q-a/58250/short-range.
We are also developing board and range is shorter than in smartphones.
But we are using Fanstel BT832XE with antenna https://www.tme.eu/Document/c4e6c41f0995bec1532828c99b9ac2ab/987651-6901.pdf.
Fact is that our board is very small (circa 40x40mm) and one sided with signals and other electronics so we have picked above external antenna.
I did even try to set: sd_ble_gap_tx_power_set(4);
We still have very short range.
What can we do to improve our range?
Best regards,
Artur
