SPI NSS Pin is set too early on send

Hello,

I try to connect a radio module using an SPI link (on SPI3, Espruino Pico, Firmware V1.90)
Here is my code :

SPI3.setup({sck:B3, miso:B4, mosi:B5, baud:10000, mode:0, order:'msb'});
var registreW = {data : 0x81, count : 1};
var modeASK = {data : 0x23, count : 1};
var returnedData;
returnedData = SPI3.send(registreW,A7);
console.log(returnedData[0]);
returnedData = SPI3.send(modeASK,A7);
console.log(returnedData[0]);

NSS Pin is A7.
Since this code doesn't work (communication doesn't work), I had a look at signals with the logic state analyzer.
I attach a screen capture. In fact, NSS PIN is set high too early, when the last byte is not totally sent. I looked at the code line 212, the PIN change seems to be executed without knowledge of end of transmission, but I can be wrong !!
Help will be greatly appreciated.
Best regards
