Question
Why receiver sensitiity of a SPBTLE-1S BLE module is only -84 dBm? Is this a typo?
Does anyone here uses SPBTLE-1S Bluetooth LE module? All the other modules from different manufactures and developers have at least -90 dBm and usually around -93 dBm. What's wrong with this module? Also datasheet of it is just awful: a lot of missing information regarding the RF part of the module such as antenna emission charts.
