Hello everyone,
I'm currently using the Nano 33 BLE Sense with the Nina B-3X module to send data packets up to 8-10 feet. However, I'm only achieving successful transmission up to 2 feet (in direct line of sight).
I'm aiming to reliably send packets without loss up to 10 feet. Is there a software-based method to increase transmission power without modifying hardware settings?.
Kindly help me with this recurring query.
Thanks.
Use a good antenna. An antenna is the best RF amplifier since ever.
Hi @grat22. One (but not the only) potential cause of unexpectedly low range is that the antenna has been damaged.
There are some surface mount capacitors on the NINA-B306 module's antenna. The antenna is at one end of the board and this position makes it more likely to receive rough handling from the user. Two of the capacitors are very close to the edge of the PCB, which makes them a bit more exposed to this. If you break one of those off then the antenna will have very poor performance.
So do a careful visual examination of the antenna. The capacitors are tiny so it can be hard to tell the difference between a populated capacitor and the pads and solder fillet remnants that might remain after the capacitor has broken off.
